Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707886, here are decompositions:

3 + 8707883 = 8707886
7 + 8707879 = 8707886
13 + 8707873 = 8707886
43 + 8707843 = 8707886
139 + 8707747 = 8707886
199 + 8707687 = 8707886
283 + 8707603 = 8707886
307 + 8707579 = 8707886

Showing the first eight; more decompositions exist.
