Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2318, here are decompositions:

  • 7 + 2311 = 2318
  • 31 + 2287 = 2318
  • 37 + 2281 = 2318
  • 67 + 2251 = 2318
  • 79 + 2239 = 2318
  • 97 + 2221 = 2318
  • 139 + 2179 = 2318
  • 157 + 2161 = 2318

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2318 first appears in π at position 16,944 of the decimal expansion (the 16,944ordinal-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.
