Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678154, here are decompositions:

5 + 8678149 = 8678154
7 + 8678147 = 8678154
13 + 8678141 = 8678154
41 + 8678113 = 8678154
61 + 8678093 = 8678154
71 + 8678083 = 8678154
73 + 8678081 = 8678154
97 + 8678057 = 8678154

Showing the first eight; more decompositions exist.
