Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755840, here are decompositions:

  • 17 + 8755823 = 8755840
  • 29 + 8755811 = 8755840
  • 59 + 8755781 = 8755840
  • 173 + 8755667 = 8755840
  • 227 + 8755613 = 8755840
  • 239 + 8755601 = 8755840
  • 281 + 8755559 = 8755840
  • 311 + 8755529 = 8755840

Showing the first eight; more decompositions exist.
