Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675142, here are decompositions:

5 + 8675137 = 8675142
29 + 8675113 = 8675142
31 + 8675111 = 8675142
43 + 8675099 = 8675142
83 + 8675059 = 8675142
89 + 8675053 = 8675142
109 + 8675033 = 8675142
131 + 8675011 = 8675142

Showing the first eight; more decompositions exist.
