Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002838, here are decompositions:

  • 17 + 1002821 = 1002838
  • 29 + 1002809 = 1002838
  • 41 + 1002797 = 1002838
  • 71 + 1002767 = 1002838
  • 191 + 1002647 = 1002838
  • 269 + 1002569 = 1002838
  • 311 + 1002527 = 1002838
  • 461 + 1002377 = 1002838

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 1,002,838 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 1002838 first appears in π at position 659,737 of the decimal expansion (the 659,737ordinal-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.
