Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140538, here are decompositions:

  • 5 + 140533 = 140538
  • 11 + 140527 = 140538
  • 17 + 140521 = 140538
  • 61 + 140477 = 140538
  • 89 + 140449 = 140538
  • 127 + 140411 = 140538
  • 131 + 140407 = 140538
  • 137 + 140401 = 140538

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 140,538 and was likely granted around 1872.

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

Position in π

The digit sequence 140538 first appears in π at position 651,700 of the decimal expansion (the 651,700ordinal-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.
