Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142700, here are decompositions:

  • 3 + 142697 = 142700
  • 43 + 142657 = 142700
  • 109 + 142591 = 142700
  • 127 + 142573 = 142700
  • 157 + 142543 = 142700
  • 163 + 142537 = 142700
  • 199 + 142501 = 142700
  • 331 + 142369 = 142700

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 142,700 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 142700 first appears in π at position 303,548 of the decimal expansion (the 303,548ordinal-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.
