Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125798, here are decompositions:

  • 7 + 125791 = 125798
  • 61 + 125737 = 125798
  • 67 + 125731 = 125798
  • 139 + 125659 = 125798
  • 157 + 125641 = 125798
  • 181 + 125617 = 125798
  • 271 + 125527 = 125798
  • 487 + 125311 = 125798

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 125,798 and was likely granted around 1871.

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

Position in π

The digit sequence 125798 first appears in π at position 341,183 of the decimal expansion (the 341,183ordinal-suffix:rd 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.
