Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12160, here are decompositions:

  • 3 + 12157 = 12160
  • 11 + 12149 = 12160
  • 17 + 12143 = 12160
  • 41 + 12119 = 12160
  • 47 + 12113 = 12160
  • 53 + 12107 = 12160
  • 59 + 12101 = 12160
  • 89 + 12071 = 12160

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12160 first appears in π at position 6,985 of the decimal expansion (the 6,985ordinal-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.
