Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757278, here are decompositions:

  • 151 + 8757127 = 8757278
  • 157 + 8757121 = 8757278
  • 241 + 8757037 = 8757278
  • 307 + 8756971 = 8757278
  • 331 + 8756947 = 8757278
  • 337 + 8756941 = 8757278
  • 571 + 8756707 = 8757278
  • 601 + 8756677 = 8757278

Showing the first eight; more decompositions exist.
