Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651788, here are decompositions:

  • 17 + 8651771 = 8651788
  • 71 + 8651717 = 8651788
  • 149 + 8651639 = 8651788
  • 179 + 8651609 = 8651788
  • 239 + 8651549 = 8651788
  • 251 + 8651537 = 8651788
  • 281 + 8651507 = 8651788
  • 359 + 8651429 = 8651788

Showing the first eight; more decompositions exist.
