Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638106, here are decompositions:

67 + 8638039 = 8638106
73 + 8638033 = 8638106
163 + 8637943 = 8638106
277 + 8637829 = 8638106
409 + 8637697 = 8638106
439 + 8637667 = 8638106
487 + 8637619 = 8638106
613 + 8637493 = 8638106

Showing the first eight; more decompositions exist.
