Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678458, here are decompositions:

  • 11 + 8678447 = 8678458
  • 59 + 8678399 = 8678458
  • 311 + 8678147 = 8678458
  • 317 + 8678141 = 8678458
  • 389 + 8678069 = 8678458
  • 401 + 8678057 = 8678458
  • 419 + 8678039 = 8678458
  • 431 + 8678027 = 8678458

Showing the first eight; more decompositions exist.
