Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657142, here are decompositions:

19 + 8657123 = 8657142
31 + 8657111 = 8657142
73 + 8657069 = 8657142
89 + 8657053 = 8657142
101 + 8657041 = 8657142
163 + 8656979 = 8657142
223 + 8656919 = 8657142
239 + 8656903 = 8657142

Showing the first eight; more decompositions exist.
