Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707146, here are decompositions:

23 + 8707123 = 8707146
43 + 8707103 = 8707146
53 + 8707093 = 8707146
89 + 8707057 = 8707146
109 + 8707037 = 8707146
139 + 8707007 = 8707146
163 + 8706983 = 8707146
167 + 8706979 = 8707146

Showing the first eight; more decompositions exist.
