Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618672, here are decompositions:

  • 79 + 8618593 = 8618672
  • 193 + 8618479 = 8618672
  • 229 + 8618443 = 8618672
  • 379 + 8618293 = 8618672
  • 421 + 8618251 = 8618672
  • 499 + 8618173 = 8618672
  • 523 + 8618149 = 8618672
  • 541 + 8618131 = 8618672

Showing the first eight; more decompositions exist.
