Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126568, here are decompositions:

  • 17 + 126551 = 126568
  • 107 + 126461 = 126568
  • 227 + 126341 = 126568
  • 251 + 126317 = 126568
  • 257 + 126311 = 126568
  • 311 + 126257 = 126568
  • 461 + 126107 = 126568
  • 521 + 126047 = 126568

Showing the first eight; more decompositions exist.
