Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618, here are decompositions:

  • 5 + 33613 = 33618
  • 17 + 33601 = 33618
  • 19 + 33599 = 33618
  • 29 + 33589 = 33618
  • 31 + 33587 = 33618
  • 37 + 33581 = 33618
  • 41 + 33577 = 33618
  • 71 + 33547 = 33618

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 33618 first appears in π at position 18,295 of the decimal expansion (the 18,295ordinal-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.
