Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478706, here are decompositions:

  • 5 + 31478701 = 31478706
  • 59 + 31478647 = 31478706
  • 67 + 31478639 = 31478706
  • 107 + 31478599 = 31478706
  • 113 + 31478593 = 31478706
  • 139 + 31478567 = 31478706
  • 223 + 31478483 = 31478706
  • 227 + 31478479 = 31478706

Showing the first eight; more decompositions exist.
