Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757128, here are decompositions:

  • 7 + 8757121 = 8757128
  • 19 + 8757109 = 8757128
  • 67 + 8757061 = 8757128
  • 109 + 8757019 = 8757128
  • 157 + 8756971 = 8757128
  • 181 + 8756947 = 8757128
  • 421 + 8756707 = 8757128
  • 439 + 8756689 = 8757128

Showing the first eight; more decompositions exist.
