Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144780, here are decompositions:

  • 7 + 144773 = 144780
  • 17 + 144763 = 144780
  • 23 + 144757 = 144780
  • 29 + 144751 = 144780
  • 43 + 144737 = 144780
  • 61 + 144719 = 144780
  • 71 + 144709 = 144780
  • 79 + 144701 = 144780

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 144,780 and was likely granted around 1873.

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

Position in π

The digit sequence 144780 first appears in π at position 940,597 of the decimal expansion (the 940,597ordinal-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.
