Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601126, here are decompositions:

  • 43 + 31601083 = 31601126
  • 103 + 31601023 = 31601126
  • 157 + 31600969 = 31601126
  • 283 + 31600843 = 31601126
  • 373 + 31600753 = 31601126
  • 409 + 31600717 = 31601126
  • 433 + 31600693 = 31601126
  • 457 + 31600669 = 31601126

Showing the first eight; more decompositions exist.
