Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142874, here are decompositions:

  • 3 + 142871 = 142874
  • 7 + 142867 = 142874
  • 37 + 142837 = 142874
  • 103 + 142771 = 142874
  • 163 + 142711 = 142874
  • 283 + 142591 = 142874
  • 307 + 142567 = 142874
  • 331 + 142543 = 142874

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 142,874 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 142874 first appears in π at position 280,033 of the decimal expansion (the 280,033ordinal-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.
