Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707690, here are decompositions:

3 + 8707687 = 8707690
29 + 8707661 = 8707690
41 + 8707649 = 8707690
59 + 8707631 = 8707690
83 + 8707607 = 8707690
269 + 8707421 = 8707690
311 + 8707379 = 8707690
347 + 8707343 = 8707690

Showing the first eight; more decompositions exist.
