Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45178, here are decompositions:

  • 17 + 45161 = 45178
  • 41 + 45137 = 45178
  • 47 + 45131 = 45178
  • 59 + 45119 = 45178
  • 101 + 45077 = 45178
  • 191 + 44987 = 45178
  • 239 + 44939 = 45178
  • 251 + 44927 = 45178

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 45178 first appears in π at position 395,648 of the decimal expansion (the 395,648ordinal-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.
