Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649850, here are decompositions:

  • 3 + 8649847 = 8649850
  • 47 + 8649803 = 8649850
  • 59 + 8649791 = 8649850
  • 89 + 8649761 = 8649850
  • 173 + 8649677 = 8649850
  • 179 + 8649671 = 8649850
  • 227 + 8649623 = 8649850
  • 239 + 8649611 = 8649850

Showing the first eight; more decompositions exist.
