Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618468, here are decompositions:

  • 139 + 8618329 = 8618468
  • 151 + 8618317 = 8618468
  • 181 + 8618287 = 8618468
  • 211 + 8618257 = 8618468
  • 337 + 8618131 = 8618468
  • 349 + 8618119 = 8618468
  • 379 + 8618089 = 8618468
  • 409 + 8618059 = 8618468

Showing the first eight; more decompositions exist.
