Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649886, here are decompositions:

  • 5 + 8649881 = 8649886
  • 17 + 8649869 = 8649886
  • 29 + 8649857 = 8649886
  • 83 + 8649803 = 8649886
  • 197 + 8649689 = 8649886
  • 257 + 8649629 = 8649886
  • 263 + 8649623 = 8649886
  • 353 + 8649533 = 8649886

Showing the first eight; more decompositions exist.
