Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645774, here are decompositions:

  • 13 + 8645761 = 8645774
  • 127 + 8645647 = 8645774
  • 157 + 8645617 = 8645774
  • 283 + 8645491 = 8645774
  • 331 + 8645443 = 8645774
  • 367 + 8645407 = 8645774
  • 421 + 8645353 = 8645774
  • 433 + 8645341 = 8645774

Showing the first eight; more decompositions exist.
