Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748878, here are decompositions:

  • 31 + 8748847 = 8748878
  • 37 + 8748841 = 8748878
  • 67 + 8748811 = 8748878
  • 139 + 8748739 = 8748878
  • 277 + 8748601 = 8748878
  • 379 + 8748499 = 8748878
  • 409 + 8748469 = 8748878
  • 547 + 8748331 = 8748878

Showing the first eight; more decompositions exist.
