Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642998, here are decompositions:

  • 47 + 8642951 = 8642998
  • 59 + 8642939 = 8642998
  • 71 + 8642927 = 8642998
  • 101 + 8642897 = 8642998
  • 137 + 8642861 = 8642998
  • 149 + 8642849 = 8642998
  • 179 + 8642819 = 8642998
  • 251 + 8642747 = 8642998

Showing the first eight; more decompositions exist.
