Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26570, here are decompositions:

  • 13 + 26557 = 26570
  • 31 + 26539 = 26570
  • 73 + 26497 = 26570
  • 139 + 26431 = 26570
  • 163 + 26407 = 26570
  • 199 + 26371 = 26570
  • 223 + 26347 = 26570
  • 277 + 26293 = 26570

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26570 first appears in π at position 91,536 of the decimal expansion (the 91,536ordinal-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.
