Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461502, here are decompositions:

  • 89 + 31461413 = 31461502
  • 311 + 31461191 = 31461502
  • 353 + 31461149 = 31461502
  • 389 + 31461113 = 31461502
  • 491 + 31461011 = 31461502
  • 719 + 31460783 = 31461502
  • 773 + 31460729 = 31461502
  • 953 + 31460549 = 31461502

Showing the first eight; more decompositions exist.
