Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720326, here are decompositions:

  • 5 + 8720321 = 8720326
  • 137 + 8720189 = 8720326
  • 149 + 8720177 = 8720326
  • 239 + 8720087 = 8720326
  • 269 + 8720057 = 8720326
  • 383 + 8719943 = 8720326
  • 479 + 8719847 = 8720326
  • 509 + 8719817 = 8720326

Showing the first eight; more decompositions exist.
