Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707942, here are decompositions:

3 + 8707939 = 8707942
59 + 8707883 = 8707942
101 + 8707841 = 8707942
149 + 8707793 = 8707942
179 + 8707763 = 8707942
281 + 8707661 = 8707942
293 + 8707649 = 8707942
311 + 8707631 = 8707942

Showing the first eight; more decompositions exist.
