Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42048, here are decompositions:

  • 5 + 42043 = 42048
  • 29 + 42019 = 42048
  • 31 + 42017 = 42048
  • 67 + 41981 = 42048
  • 79 + 41969 = 42048
  • 89 + 41959 = 42048
  • 101 + 41947 = 42048
  • 107 + 41941 = 42048

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42048 first appears in π at position 199,283 of the decimal expansion (the 199,283ordinal-suffix:rd 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.
