Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26616, here are decompositions:

  • 19 + 26597 = 26616
  • 43 + 26573 = 26616
  • 59 + 26557 = 26616
  • 103 + 26513 = 26616
  • 127 + 26489 = 26616
  • 137 + 26479 = 26616
  • 157 + 26459 = 26616
  • 167 + 26449 = 26616

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26616 first appears in π at position 233,021 of the decimal expansion (the 233,021ordinal-suffix:st 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.
