Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987750, here are decompositions:

11 + 987739 = 987750
37 + 987713 = 987750
53 + 987697 = 987750
151 + 987599 = 987750
157 + 987593 = 987750
163 + 987587 = 987750
191 + 987559 = 987750
227 + 987523 = 987750

Showing the first eight; more decompositions exist.
