Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748688, here are decompositions:

  • 41 + 8748647 = 8748688
  • 89 + 8748599 = 8748688
  • 101 + 8748587 = 8748688
  • 107 + 8748581 = 8748688
  • 257 + 8748431 = 8748688
  • 269 + 8748419 = 8748688
  • 359 + 8748329 = 8748688
  • 401 + 8748287 = 8748688

Showing the first eight; more decompositions exist.
