Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601030, here are decompositions:

  • 7 + 31601023 = 31601030
  • 37 + 31600993 = 31601030
  • 61 + 31600969 = 31601030
  • 73 + 31600957 = 31601030
  • 229 + 31600801 = 31601030
  • 277 + 31600753 = 31601030
  • 313 + 31600717 = 31601030
  • 337 + 31600693 = 31601030

Showing the first eight; more decompositions exist.
