Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700902, here are decompositions:

31 + 8700871 = 8700902
103 + 8700799 = 8700902
109 + 8700793 = 8700902
151 + 8700751 = 8700902
181 + 8700721 = 8700902
193 + 8700709 = 8700902
313 + 8700589 = 8700902
373 + 8700529 = 8700902

Showing the first eight; more decompositions exist.
