Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645564, here are decompositions:

  • 73 + 8645491 = 8645564
  • 157 + 8645407 = 8645564
  • 211 + 8645353 = 8645564
  • 223 + 8645341 = 8645564
  • 271 + 8645293 = 8645564
  • 283 + 8645281 = 8645564
  • 307 + 8645257 = 8645564
  • 541 + 8645023 = 8645564

Showing the first eight; more decompositions exist.
