Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648142, here are decompositions:

11 + 8648131 = 8648142
29 + 8648113 = 8648142
31 + 8648111 = 8648142
43 + 8648099 = 8648142
59 + 8648083 = 8648142
109 + 8648033 = 8648142
149 + 8647993 = 8648142
163 + 8647979 = 8648142

Showing the first eight; more decompositions exist.
