Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638046, here are decompositions:

3 + 8638043 = 8638046
7 + 8638039 = 8638046
13 + 8638033 = 8638046
73 + 8637973 = 8638046
103 + 8637943 = 8638046
199 + 8637847 = 8638046
349 + 8637697 = 8638046
379 + 8637667 = 8638046

Showing the first eight; more decompositions exist.
