Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638482, here are decompositions:

5 + 8638477 = 8638482
11 + 8638471 = 8638482
19 + 8638463 = 8638482
29 + 8638453 = 8638482
31 + 8638451 = 8638482
71 + 8638411 = 8638482
79 + 8638403 = 8638482
101 + 8638381 = 8638482

Showing the first eight; more decompositions exist.
