Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476272, here are decompositions:

  • 103 + 31476169 = 31476272
  • 199 + 31476073 = 31476272
  • 241 + 31476031 = 31476272
  • 523 + 31475749 = 31476272
  • 661 + 31475611 = 31476272
  • 673 + 31475599 = 31476272
  • 691 + 31475581 = 31476272
  • 829 + 31475443 = 31476272

Showing the first eight; more decompositions exist.
