Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755780, here are decompositions:

  • 113 + 8755667 = 8755780
  • 167 + 8755613 = 8755780
  • 179 + 8755601 = 8755780
  • 251 + 8755529 = 8755780
  • 263 + 8755517 = 8755780
  • 281 + 8755499 = 8755780
  • 311 + 8755469 = 8755780
  • 401 + 8755379 = 8755780

Showing the first eight; more decompositions exist.
