Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26486, here are decompositions:

  • 7 + 26479 = 26486
  • 37 + 26449 = 26486
  • 79 + 26407 = 26486
  • 139 + 26347 = 26486
  • 193 + 26293 = 26486
  • 223 + 26263 = 26486
  • 277 + 26209 = 26486
  • 283 + 26203 = 26486

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26486 first appears in π at position 68,214 of the decimal expansion (the 68,214ordinal-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.
