Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26166, here are decompositions:

  • 5 + 26161 = 26166
  • 13 + 26153 = 26166
  • 47 + 26119 = 26166
  • 53 + 26113 = 26166
  • 59 + 26107 = 26166
  • 67 + 26099 = 26166
  • 83 + 26083 = 26166
  • 113 + 26053 = 26166

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26166 first appears in π at position 31,116 of the decimal expansion (the 31,116ordinal-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.
