Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678156, here are decompositions:

7 + 8678149 = 8678156
43 + 8678113 = 8678156
73 + 8678083 = 8678156
103 + 8678053 = 8678156
127 + 8678029 = 8678156
163 + 8677993 = 8678156
397 + 8677759 = 8678156
433 + 8677723 = 8678156

Showing the first eight; more decompositions exist.
