Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101212, here are decompositions:

  • 3 + 101209 = 101212
  • 5 + 101207 = 101212
  • 29 + 101183 = 101212
  • 53 + 101159 = 101212
  • 71 + 101141 = 101212
  • 101 + 101111 = 101212
  • 131 + 101081 = 101212
  • 149 + 101063 = 101212

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 101,212 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 101212 first appears in π at position 86,313 of the decimal expansion (the 86,313ordinal-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.
