Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4018, here are decompositions:

  • 5 + 4013 = 4018
  • 11 + 4007 = 4018
  • 17 + 4001 = 4018
  • 29 + 3989 = 4018
  • 71 + 3947 = 4018
  • 89 + 3929 = 4018
  • 101 + 3917 = 4018
  • 107 + 3911 = 4018

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 4018 first appears in π at position 18,368 of the decimal expansion (the 18,368ordinal-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.
