Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987310, here are decompositions:

11 + 987299 = 987310
17 + 987293 = 987310
59 + 987251 = 987310
83 + 987227 = 987310
101 + 987209 = 987310
167 + 987143 = 987310
227 + 987083 = 987310
257 + 987053 = 987310

Showing the first eight; more decompositions exist.
