Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16478, here are decompositions:

  • 31 + 16447 = 16478
  • 61 + 16417 = 16478
  • 67 + 16411 = 16478
  • 97 + 16381 = 16478
  • 109 + 16369 = 16478
  • 139 + 16339 = 16478
  • 211 + 16267 = 16478
  • 229 + 16249 = 16478

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16478 first appears in π at position 14,313 of the decimal expansion (the 14,313ordinal-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.
