Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144862, here are decompositions:

  • 23 + 144839 = 144862
  • 71 + 144791 = 144862
  • 83 + 144779 = 144862
  • 89 + 144773 = 144862
  • 131 + 144731 = 144862
  • 191 + 144671 = 144862
  • 233 + 144629 = 144862
  • 251 + 144611 = 144862

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 144,862 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 144862 first appears in π at position 134,570 of the decimal expansion (the 134,570ordinal-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.
