Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707040, here are decompositions:

3 + 8707037 = 8707040
19 + 8707021 = 8707040
37 + 8707003 = 8707040
61 + 8706979 = 8707040
73 + 8706967 = 8707040
79 + 8706961 = 8707040
103 + 8706937 = 8707040
211 + 8706829 = 8707040

Showing the first eight; more decompositions exist.
