Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707818, here are decompositions:

37 + 8707781 = 8707818
71 + 8707747 = 8707818
107 + 8707711 = 8707818
131 + 8707687 = 8707818
149 + 8707669 = 8707818
157 + 8707661 = 8707818
167 + 8707651 = 8707818
211 + 8707607 = 8707818

Showing the first eight; more decompositions exist.
