Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618122, here are decompositions:

  • 3 + 8618119 = 8618122
  • 59 + 8618063 = 8618122
  • 89 + 8618033 = 8618122
  • 101 + 8618021 = 8618122
  • 131 + 8617991 = 8618122
  • 173 + 8617949 = 8618122
  • 179 + 8617943 = 8618122
  • 251 + 8617871 = 8618122

Showing the first eight; more decompositions exist.
