Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745624, here are decompositions:

11 + 8745613 = 8745624
53 + 8745571 = 8745624
67 + 8745557 = 8745624
71 + 8745553 = 8745624
73 + 8745551 = 8745624
101 + 8745523 = 8745624
131 + 8745493 = 8745624
257 + 8745367 = 8745624

Showing the first eight; more decompositions exist.
