Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667690, here are decompositions:

  • 13 + 8667677 = 8667690
  • 29 + 8667661 = 8667690
  • 37 + 8667653 = 8667690
  • 79 + 8667611 = 8667690
  • 89 + 8667601 = 8667690
  • 127 + 8667563 = 8667690
  • 131 + 8667559 = 8667690
  • 151 + 8667539 = 8667690

Showing the first eight; more decompositions exist.
