Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625186, here are decompositions:

  • 7 + 31625179 = 31625186
  • 37 + 31625149 = 31625186
  • 127 + 31625059 = 31625186
  • 337 + 31624849 = 31625186
  • 349 + 31624837 = 31625186
  • 379 + 31624807 = 31625186
  • 433 + 31624753 = 31625186
  • 487 + 31624699 = 31625186

Showing the first eight; more decompositions exist.
