Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616380, here are decompositions:

  • 7 + 8616373 = 8616380
  • 43 + 8616337 = 8616380
  • 61 + 8616319 = 8616380
  • 109 + 8616271 = 8616380
  • 139 + 8616241 = 8616380
  • 163 + 8616217 = 8616380
  • 181 + 8616199 = 8616380
  • 193 + 8616187 = 8616380

Showing the first eight; more decompositions exist.
