Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987716, here are decompositions:

3 + 987713 = 987716
19 + 987697 = 987716
109 + 987607 = 987716
157 + 987559 = 987716
193 + 987523 = 987716
283 + 987433 = 987716
523 + 987193 = 987716
619 + 987097 = 987716

Showing the first eight; more decompositions exist.
