Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638524, here are decompositions:

7 + 8638517 = 8638524
43 + 8638481 = 8638524
47 + 8638477 = 8638524
53 + 8638471 = 8638524
61 + 8638463 = 8638524
67 + 8638457 = 8638524
71 + 8638453 = 8638524
73 + 8638451 = 8638524

Showing the first eight; more decompositions exist.
