Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18776, here are decompositions:

  • 3 + 18773 = 18776
  • 19 + 18757 = 18776
  • 97 + 18679 = 18776
  • 139 + 18637 = 18776
  • 193 + 18583 = 18776
  • 223 + 18553 = 18776
  • 283 + 18493 = 18776
  • 337 + 18439 = 18776

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18776 first appears in π at position 268,390 of the decimal expansion (the 268,390ordinal-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.
