Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475684, here are decompositions:

  • 3 + 31475681 = 31475684
  • 7 + 31475677 = 31475684
  • 61 + 31475623 = 31475684
  • 73 + 31475611 = 31475684
  • 103 + 31475581 = 31475684
  • 193 + 31475491 = 31475684
  • 241 + 31475443 = 31475684
  • 277 + 31475407 = 31475684

Showing the first eight; more decompositions exist.
