Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738870, here are decompositions:

  • 31 + 8738839 = 8738870
  • 61 + 8738809 = 8738870
  • 103 + 8738767 = 8738870
  • 157 + 8738713 = 8738870
  • 163 + 8738707 = 8738870
  • 199 + 8738671 = 8738870
  • 211 + 8738659 = 8738870
  • 229 + 8738641 = 8738870

Showing the first eight; more decompositions exist.
