Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497260, here are decompositions:

  • 31 + 31497229 = 31497260
  • 37 + 31497223 = 31497260
  • 73 + 31497187 = 31497260
  • 103 + 31497157 = 31497260
  • 127 + 31497133 = 31497260
  • 271 + 31496989 = 31497260
  • 283 + 31496977 = 31497260
  • 313 + 31496947 = 31497260

Showing the first eight; more decompositions exist.
