Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121406, here are decompositions:

  • 3 + 121403 = 121406
  • 37 + 121369 = 121406
  • 73 + 121333 = 121406
  • 79 + 121327 = 121406
  • 97 + 121309 = 121406
  • 139 + 121267 = 121406
  • 283 + 121123 = 121406
  • 367 + 121039 = 121406

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 121,406 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 121406 first appears in π at position 20,089 of the decimal expansion (the 20,089ordinal-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.
