Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17910, here are decompositions:

  • 7 + 17903 = 17910
  • 19 + 17891 = 17910
  • 29 + 17881 = 17910
  • 47 + 17863 = 17910
  • 59 + 17851 = 17910
  • 71 + 17839 = 17910
  • 73 + 17837 = 17910
  • 83 + 17827 = 17910

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17910 first appears in π at position 4,094 of the decimal expansion (the 4,094ordinal-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.
