Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624142, here are decompositions:

5 + 8624137 = 8624142
11 + 8624131 = 8624142
13 + 8624129 = 8624142
31 + 8624111 = 8624142
41 + 8624101 = 8624142
83 + 8624059 = 8624142
139 + 8624003 = 8624142
173 + 8623969 = 8624142

Showing the first eight; more decompositions exist.
