Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678550, here are decompositions:

  • 31 + 8678519 = 8678550
  • 43 + 8678507 = 8678550
  • 103 + 8678447 = 8678550
  • 151 + 8678399 = 8678550
  • 157 + 8678393 = 8678550
  • 191 + 8678359 = 8678550
  • 197 + 8678353 = 8678550
  • 211 + 8678339 = 8678550

Showing the first eight; more decompositions exist.
