Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758642, here are decompositions:

  • 5 + 8758637 = 8758642
  • 59 + 8758583 = 8758642
  • 131 + 8758511 = 8758642
  • 251 + 8758391 = 8758642
  • 281 + 8758361 = 8758642
  • 353 + 8758289 = 8758642
  • 443 + 8758199 = 8758642
  • 593 + 8758049 = 8758642

Showing the first eight; more decompositions exist.
