Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26158, here are decompositions:

  • 5 + 26153 = 26158
  • 17 + 26141 = 26158
  • 47 + 26111 = 26158
  • 59 + 26099 = 26158
  • 137 + 26021 = 26158
  • 227 + 25931 = 26158
  • 239 + 25919 = 26158
  • 269 + 25889 = 26158

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26158 first appears in π at position 69,601 of the decimal expansion (the 69,601ordinal-suffix:st 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.
