Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615016, here are decompositions:

  • 3 + 31615013 = 31615016
  • 73 + 31614943 = 31615016
  • 127 + 31614889 = 31615016
  • 157 + 31614859 = 31615016
  • 163 + 31614853 = 31615016
  • 229 + 31614787 = 31615016
  • 283 + 31614733 = 31615016
  • 313 + 31614703 = 31615016

Showing the first eight; more decompositions exist.
