Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122000, here are decompositions:

  • 3 + 121997 = 122000
  • 7 + 121993 = 122000
  • 37 + 121963 = 122000
  • 79 + 121921 = 122000
  • 157 + 121843 = 122000
  • 211 + 121789 = 122000
  • 313 + 121687 = 122000
  • 367 + 121633 = 122000

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 122,000 and was likely granted around 1871.

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

Position in π

The digit sequence 122000 first appears in π at position 930,947 of the decimal expansion (the 930,947ordinal-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.
