Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987682, here are decompositions:

23 + 987659 = 987682
83 + 987599 = 987682
89 + 987593 = 987682
149 + 987533 = 987682
173 + 987509 = 987682
191 + 987491 = 987682
383 + 987299 = 987682
389 + 987293 = 987682

Showing the first eight; more decompositions exist.
