Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748420, here are decompositions:

  • 7 + 8748413 = 8748420
  • 17 + 8748403 = 8748420
  • 53 + 8748367 = 8748420
  • 59 + 8748361 = 8748420
  • 61 + 8748359 = 8748420
  • 89 + 8748331 = 8748420
  • 97 + 8748323 = 8748420
  • 139 + 8748281 = 8748420

Showing the first eight; more decompositions exist.
