Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11616, here are decompositions:

  • 19 + 11597 = 11616
  • 23 + 11593 = 11616
  • 29 + 11587 = 11616
  • 37 + 11579 = 11616
  • 67 + 11549 = 11616
  • 89 + 11527 = 11616
  • 97 + 11519 = 11616
  • 113 + 11503 = 11616

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11616 first appears in π at position 29,849 of the decimal expansion (the 29,849ordinal-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.
