Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003280, here are decompositions:

  • 7 + 1003273 = 1003280
  • 79 + 1003201 = 1003280
  • 139 + 1003141 = 1003280
  • 193 + 1003087 = 1003280
  • 241 + 1003039 = 1003280
  • 277 + 1003003 = 1003280
  • 307 + 1002973 = 1003280
  • 349 + 1002931 = 1003280

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,003,280 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 1003280 first appears in π at position 629,055 of the decimal expansion (the 629,055ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
