Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2390, here are decompositions:

  • 7 + 2383 = 2390
  • 13 + 2377 = 2390
  • 19 + 2371 = 2390
  • 43 + 2347 = 2390
  • 79 + 2311 = 2390
  • 97 + 2293 = 2390
  • 103 + 2287 = 2390
  • 109 + 2281 = 2390

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2390 first appears in π at position 1,688 of the decimal expansion (the 1,688ordinal-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.
