Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657138, here are decompositions:

97 + 8657041 = 8657138
199 + 8656939 = 8657138
241 + 8656897 = 8657138
307 + 8656831 = 8657138
331 + 8656807 = 8657138
337 + 8656801 = 8657138
379 + 8656759 = 8657138
409 + 8656729 = 8657138

Showing the first eight; more decompositions exist.
