Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143812, here are decompositions:

  • 5 + 143807 = 143812
  • 83 + 143729 = 143812
  • 101 + 143711 = 143812
  • 113 + 143699 = 143812
  • 239 + 143573 = 143812
  • 293 + 143519 = 143812
  • 311 + 143501 = 143812
  • 479 + 143333 = 143812

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 143,812 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 143812 first appears in π at position 569,127 of the decimal expansion (the 569,127ordinal-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.
