Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707668, here are decompositions:

7 + 8707661 = 8707668
17 + 8707651 = 8707668
19 + 8707649 = 8707668
37 + 8707631 = 8707668
61 + 8707607 = 8707668
89 + 8707579 = 8707668
131 + 8707537 = 8707668
191 + 8707477 = 8707668

Showing the first eight; more decompositions exist.
