Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616216, here are decompositions:

  • 13 + 8616203 = 8616216
  • 17 + 8616199 = 8616216
  • 19 + 8616197 = 8616216
  • 29 + 8616187 = 8616216
  • 43 + 8616173 = 8616216
  • 47 + 8616169 = 8616216
  • 67 + 8616149 = 8616216
  • 127 + 8616089 = 8616216

Showing the first eight; more decompositions exist.
