Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758438, here are decompositions:

  • 5 + 8758433 = 8758438
  • 11 + 8758427 = 8758438
  • 47 + 8758391 = 8758438
  • 149 + 8758289 = 8758438
  • 239 + 8758199 = 8758438
  • 251 + 8758187 = 8758438
  • 281 + 8758157 = 8758438
  • 389 + 8758049 = 8758438

Showing the first eight; more decompositions exist.
