Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624760, here are decompositions:

  • 7 + 31624753 = 31624760
  • 19 + 31624741 = 31624760
  • 43 + 31624717 = 31624760
  • 61 + 31624699 = 31624760
  • 163 + 31624597 = 31624760
  • 283 + 31624477 = 31624760
  • 331 + 31624429 = 31624760
  • 337 + 31624423 = 31624760

Showing the first eight; more decompositions exist.
