Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26816, here are decompositions:

  • 3 + 26813 = 26816
  • 79 + 26737 = 26816
  • 103 + 26713 = 26816
  • 277 + 26539 = 26816
  • 337 + 26479 = 26816
  • 367 + 26449 = 26816
  • 379 + 26437 = 26816
  • 409 + 26407 = 26816

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26816 first appears in π at position 50,112 of the decimal expansion (the 50,112ordinal-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.
