Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738856, here are decompositions:

  • 13 + 8738843 = 8738856
  • 17 + 8738839 = 8738856
  • 19 + 8738837 = 8738856
  • 43 + 8738813 = 8738856
  • 47 + 8738809 = 8738856
  • 73 + 8738783 = 8738856
  • 89 + 8738767 = 8738856
  • 97 + 8738759 = 8738856

Showing the first eight; more decompositions exist.
