Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6478, here are decompositions:

  • 5 + 6473 = 6478
  • 29 + 6449 = 6478
  • 89 + 6389 = 6478
  • 149 + 6329 = 6478
  • 167 + 6311 = 6478
  • 179 + 6299 = 6478
  • 191 + 6287 = 6478
  • 257 + 6221 = 6478

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 6478 first appears in π at position 10,657 of the decimal expansion (the 10,657ordinal-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.
