Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142954, here are decompositions:

  • 5 + 142949 = 142954
  • 47 + 142907 = 142954
  • 83 + 142871 = 142954
  • 113 + 142841 = 142954
  • 167 + 142787 = 142954
  • 197 + 142757 = 142954
  • 257 + 142697 = 142954
  • 281 + 142673 = 142954

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 142,954 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 142954 first appears in π at position 323,328 of the decimal expansion (the 323,328ordinal-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.
