Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678138, here are decompositions:

109 + 8678029 = 8678138
127 + 8678011 = 8678138
367 + 8677771 = 8678138
379 + 8677759 = 8678138
457 + 8677681 = 8678138
487 + 8677651 = 8678138
661 + 8677477 = 8678138
739 + 8677399 = 8678138

Showing the first eight; more decompositions exist.
