Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11908, here are decompositions:

  • 5 + 11903 = 11908
  • 11 + 11897 = 11908
  • 41 + 11867 = 11908
  • 101 + 11807 = 11908
  • 107 + 11801 = 11908
  • 131 + 11777 = 11908
  • 191 + 11717 = 11908
  • 227 + 11681 = 11908

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11908 first appears in π at position 43,226 of the decimal expansion (the 43,226ordinal-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.
