Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625826, here are decompositions:

  • 5 + 31625821 = 31625826
  • 7 + 31625819 = 31625826
  • 19 + 31625807 = 31625826
  • 47 + 31625779 = 31625826
  • 53 + 31625773 = 31625826
  • 59 + 31625767 = 31625826
  • 73 + 31625753 = 31625826
  • 103 + 31625723 = 31625826

Showing the first eight; more decompositions exist.
