Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987402, here are decompositions:

11 + 987391 = 987402
19 + 987383 = 987402
41 + 987361 = 987402
89 + 987313 = 987402
103 + 987299 = 987402
109 + 987293 = 987402
151 + 987251 = 987402
191 + 987211 = 987402

Showing the first eight; more decompositions exist.
