Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497626, here are decompositions:

  • 67 + 31497559 = 31497626
  • 79 + 31497547 = 31497626
  • 103 + 31497523 = 31497626
  • 157 + 31497469 = 31497626
  • 163 + 31497463 = 31497626
  • 313 + 31497313 = 31497626
  • 397 + 31497229 = 31497626
  • 439 + 31497187 = 31497626

Showing the first eight; more decompositions exist.
