Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26290, here are decompositions:

  • 23 + 26267 = 26290
  • 29 + 26261 = 26290
  • 41 + 26249 = 26290
  • 53 + 26237 = 26290
  • 101 + 26189 = 26290
  • 107 + 26183 = 26290
  • 113 + 26177 = 26290
  • 137 + 26153 = 26290

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26290 first appears in π at position 139,397 of the decimal expansion (the 139,397ordinal-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.
