Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707140, here are decompositions:

17 + 8707123 = 8707140
37 + 8707103 = 8707140
47 + 8707093 = 8707140
83 + 8707057 = 8707140
103 + 8707037 = 8707140
109 + 8707031 = 8707140
137 + 8707003 = 8707140
157 + 8706983 = 8707140

Showing the first eight; more decompositions exist.
