Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987354, here are decompositions:

41 + 987313 = 987354
61 + 987293 = 987354
103 + 987251 = 987354
127 + 987227 = 987354
163 + 987191 = 987354
211 + 987143 = 987354
227 + 987127 = 987354
257 + 987097 = 987354

Showing the first eight; more decompositions exist.
