Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707788, here are decompositions:

7 + 8707781 = 8707788
41 + 8707747 = 8707788
101 + 8707687 = 8707788
127 + 8707661 = 8707788
137 + 8707651 = 8707788
139 + 8707649 = 8707788
157 + 8707631 = 8707788
181 + 8707607 = 8707788

Showing the first eight; more decompositions exist.
