Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987378, here are decompositions:

17 + 987361 = 987378
79 + 987299 = 987378
127 + 987251 = 987378
151 + 987227 = 987378
167 + 987211 = 987378
179 + 987199 = 987378
251 + 987127 = 987378
277 + 987101 = 987378

Showing the first eight; more decompositions exist.
