Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515326, here are decompositions:

  • 19 + 31515307 = 31515326
  • 43 + 31515283 = 31515326
  • 109 + 31515217 = 31515326
  • 379 + 31514947 = 31515326
  • 433 + 31514893 = 31515326
  • 457 + 31514869 = 31515326
  • 487 + 31514839 = 31515326
  • 673 + 31514653 = 31515326

Showing the first eight; more decompositions exist.
