Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17850, here are decompositions:

  • 11 + 17839 = 17850
  • 13 + 17837 = 17850
  • 23 + 17827 = 17850
  • 43 + 17807 = 17850
  • 59 + 17791 = 17850
  • 61 + 17789 = 17850
  • 67 + 17783 = 17850
  • 89 + 17761 = 17850

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17850 first appears in π at position 12,150 of the decimal expansion (the 12,150ordinal-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.
