Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142944, here are decompositions:

  • 5 + 142939 = 142944
  • 37 + 142907 = 142944
  • 41 + 142903 = 142944
  • 47 + 142897 = 142944
  • 71 + 142873 = 142944
  • 73 + 142871 = 142944
  • 103 + 142841 = 142944
  • 107 + 142837 = 142944

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 142,944 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 142944 first appears in π at position 688,224 of the decimal expansion (the 688,224ordinal-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.
