Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715940, here are decompositions:

3 + 8715937 = 8715940
53 + 8715887 = 8715940
59 + 8715881 = 8715940
179 + 8715761 = 8715940
269 + 8715671 = 8715940
281 + 8715659 = 8715940
293 + 8715647 = 8715940
353 + 8715587 = 8715940

Showing the first eight; more decompositions exist.
