Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601046, here are decompositions:

  • 5 + 31601041 = 31601046
  • 23 + 31601023 = 31601046
  • 53 + 31600993 = 31601046
  • 89 + 31600957 = 31601046
  • 163 + 31600883 = 31601046
  • 223 + 31600823 = 31601046
  • 229 + 31600817 = 31601046
  • 263 + 31600783 = 31601046

Showing the first eight; more decompositions exist.
