Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621030, here are decompositions:

  • 13 + 8621017 = 8621030
  • 37 + 8620993 = 8621030
  • 79 + 8620951 = 8621030
  • 157 + 8620873 = 8621030
  • 283 + 8620747 = 8621030
  • 307 + 8620723 = 8621030
  • 367 + 8620663 = 8621030
  • 409 + 8620621 = 8621030

Showing the first eight; more decompositions exist.
