Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86426, here are decompositions:

  • 3 + 86423 = 86426
  • 13 + 86413 = 86426
  • 37 + 86389 = 86426
  • 73 + 86353 = 86426
  • 103 + 86323 = 86426
  • 139 + 86287 = 86426
  • 157 + 86269 = 86426
  • 163 + 86263 = 86426

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 86426 first appears in π at position 3,930 of the decimal expansion (the 3,930ordinal-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.
