Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638476, here are decompositions:

5 + 8638471 = 8638476
13 + 8638463 = 8638476
19 + 8638457 = 8638476
23 + 8638453 = 8638476
29 + 8638447 = 8638476
73 + 8638403 = 8638476
97 + 8638379 = 8638476
103 + 8638373 = 8638476

Showing the first eight; more decompositions exist.
