Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707786, here are decompositions:

5 + 8707781 = 8707786
23 + 8707763 = 8707786
89 + 8707697 = 8707786
137 + 8707649 = 8707786
179 + 8707607 = 8707786
443 + 8707343 = 8707786
509 + 8707277 = 8707786
683 + 8707103 = 8707786

Showing the first eight; more decompositions exist.
