Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16616, here are decompositions:

  • 13 + 16603 = 16616
  • 43 + 16573 = 16616
  • 97 + 16519 = 16616
  • 139 + 16477 = 16616
  • 163 + 16453 = 16616
  • 199 + 16417 = 16616
  • 277 + 16339 = 16616
  • 283 + 16333 = 16616

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16616 first appears in π at position 37,916 of the decimal expansion (the 37,916ordinal-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.
