Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6424, here are decompositions:

  • 3 + 6421 = 6424
  • 71 + 6353 = 6424
  • 101 + 6323 = 6424
  • 107 + 6317 = 6424
  • 113 + 6311 = 6424
  • 137 + 6287 = 6424
  • 167 + 6257 = 6424
  • 227 + 6197 = 6424

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 6424 first appears in π at position 24,778 of the decimal expansion (the 24,778ordinal-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.
