Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8418, here are decompositions:

  • 29 + 8389 = 8418
  • 31 + 8387 = 8418
  • 41 + 8377 = 8418
  • 89 + 8329 = 8418
  • 101 + 8317 = 8418
  • 107 + 8311 = 8418
  • 127 + 8291 = 8418
  • 131 + 8287 = 8418

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8418 first appears in π at position 20,804 of the decimal expansion (the 20,804ordinal-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.
