Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26860, here are decompositions:

  • 11 + 26849 = 26860
  • 47 + 26813 = 26860
  • 59 + 26801 = 26860
  • 83 + 26777 = 26860
  • 101 + 26759 = 26860
  • 131 + 26729 = 26860
  • 137 + 26723 = 26860
  • 149 + 26711 = 26860

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26860 first appears in π at position 6,210 of the decimal expansion (the 6,210ordinal-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.
