Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538340, here are decompositions:

  • 7 + 538333 = 538340
  • 31 + 538309 = 538340
  • 37 + 538303 = 538340
  • 43 + 538297 = 538340
  • 73 + 538267 = 538340
  • 139 + 538201 = 538340
  • 181 + 538159 = 538340
  • 193 + 538147 = 538340

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 538,340 and was likely granted around 1894.

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

Position in π

The digit sequence 538340 first appears in π at position 523,818 of the decimal expansion (the 523,818ordinal-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.
