Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638304, here are decompositions:

13 + 8638291 = 8638304
67 + 8638237 = 8638304
97 + 8638207 = 8638304
271 + 8638033 = 8638304
313 + 8637991 = 8638304
331 + 8637973 = 8638304
457 + 8637847 = 8638304
607 + 8637697 = 8638304

Showing the first eight; more decompositions exist.
