Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525140, here are decompositions:

  • 3 + 525137 = 525140
  • 13 + 525127 = 525140
  • 97 + 525043 = 525140
  • 127 + 525013 = 525140
  • 139 + 525001 = 525140
  • 157 + 524983 = 525140
  • 181 + 524959 = 525140
  • 193 + 524947 = 525140

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 525,140 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 525140 first appears in π at position 916,098 of the decimal expansion (the 916,098ordinal-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.
