Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649982, here are decompositions:

  • 53 + 8649929 = 8649982
  • 71 + 8649911 = 8649982
  • 101 + 8649881 = 8649982
  • 113 + 8649869 = 8649982
  • 179 + 8649803 = 8649982
  • 191 + 8649791 = 8649982
  • 293 + 8649689 = 8649982
  • 311 + 8649671 = 8649982

Showing the first eight; more decompositions exist.
