Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678142, here are decompositions:

13 + 8678129 = 8678142
29 + 8678113 = 8678142
59 + 8678083 = 8678142
61 + 8678081 = 8678142
73 + 8678069 = 8678142
79 + 8678063 = 8678142
89 + 8678053 = 8678142
103 + 8678039 = 8678142

Showing the first eight; more decompositions exist.
