Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638116, here are decompositions:

73 + 8638043 = 8638116
83 + 8638033 = 8638116
163 + 8637953 = 8638116
173 + 8637943 = 8638116
269 + 8637847 = 8638116
337 + 8637779 = 8638116
367 + 8637749 = 8638116
419 + 8637697 = 8638116

Showing the first eight; more decompositions exist.
