Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142850, here are decompositions:

  • 13 + 142837 = 142850
  • 61 + 142789 = 142850
  • 79 + 142771 = 142850
  • 139 + 142711 = 142850
  • 151 + 142699 = 142850
  • 193 + 142657 = 142850
  • 241 + 142609 = 142850
  • 277 + 142573 = 142850

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 142,850 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 142850 first appears in π at position 882,982 of the decimal expansion (the 882,982ordinal-suffix:nd 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.
