Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655558, here are decompositions:

  • 31 + 8655527 = 8655558
  • 61 + 8655497 = 8655558
  • 101 + 8655457 = 8655558
  • 137 + 8655421 = 8655558
  • 157 + 8655401 = 8655558
  • 227 + 8655331 = 8655558
  • 251 + 8655307 = 8655558
  • 271 + 8655287 = 8655558

Showing the first eight; more decompositions exist.
