Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17898, here are decompositions:

  • 7 + 17891 = 17898
  • 17 + 17881 = 17898
  • 47 + 17851 = 17898
  • 59 + 17839 = 17898
  • 61 + 17837 = 17898
  • 71 + 17827 = 17898
  • 107 + 17791 = 17898
  • 109 + 17789 = 17898

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17898 first appears in π at position 149,863 of the decimal expansion (the 149,863ordinal-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.
