Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17804, here are decompositions:

  • 13 + 17791 = 17804
  • 43 + 17761 = 17804
  • 67 + 17737 = 17804
  • 97 + 17707 = 17804
  • 181 + 17623 = 17804
  • 223 + 17581 = 17804
  • 307 + 17497 = 17804
  • 313 + 17491 = 17804

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17804 first appears in π at position 61,073 of the decimal expansion (the 61,073ordinal-suffix:rd 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.
