Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475280, here are decompositions:

  • 7 + 475273 = 475280
  • 37 + 475243 = 475280
  • 61 + 475219 = 475280
  • 73 + 475207 = 475280
  • 139 + 475141 = 475280
  • 199 + 475081 = 475280
  • 229 + 475051 = 475280
  • 331 + 474949 = 475280

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 475,280 and was likely granted around 1892.

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

Position in π

The digit sequence 475280 first appears in π at position 251,050 of the decimal expansion (the 251,050ordinal-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.
