Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718480, here are decompositions:

11 + 8718469 = 8718480
19 + 8718461 = 8718480
41 + 8718439 = 8718480
53 + 8718427 = 8718480
61 + 8718419 = 8718480
73 + 8718407 = 8718480
79 + 8718401 = 8718480
103 + 8718377 = 8718480

Showing the first eight; more decompositions exist.
