Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987850, here are decompositions:

29 + 987821 = 987850
41 + 987809 = 987850
47 + 987803 = 987850
53 + 987797 = 987850
137 + 987713 = 987850
191 + 987659 = 987850
251 + 987599 = 987850
257 + 987593 = 987850

Showing the first eight; more decompositions exist.
