Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987350, here are decompositions:

37 + 987313 = 987350
139 + 987211 = 987350
151 + 987199 = 987350
157 + 987193 = 987350
223 + 987127 = 987350
271 + 987079 = 987350
283 + 987067 = 987350
307 + 987043 = 987350

Showing the first eight; more decompositions exist.
