Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55018, here are decompositions:

  • 17 + 55001 = 55018
  • 59 + 54959 = 55018
  • 101 + 54917 = 55018
  • 137 + 54881 = 55018
  • 149 + 54869 = 55018
  • 167 + 54851 = 55018
  • 239 + 54779 = 55018
  • 251 + 54767 = 55018

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 55018 first appears in π at position 256,060 of the decimal expansion (the 256,060ordinal-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.
