Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672142, here are decompositions:

41 + 8672101 = 8672142
43 + 8672099 = 8672142
79 + 8672063 = 8672142
139 + 8672003 = 8672142
151 + 8671991 = 8672142
163 + 8671979 = 8672142
223 + 8671919 = 8672142
331 + 8671811 = 8672142

Showing the first eight; more decompositions exist.
