Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42418, here are decompositions:

  • 11 + 42407 = 42418
  • 59 + 42359 = 42418
  • 137 + 42281 = 42418
  • 179 + 42239 = 42418
  • 191 + 42227 = 42418
  • 197 + 42221 = 42418
  • 239 + 42179 = 42418
  • 317 + 42101 = 42418

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42418 first appears in π at position 278,752 of the decimal expansion (the 278,752ordinal-suffix:nd 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.
