Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987230, here are decompositions:

3 + 987227 = 987230
19 + 987211 = 987230
31 + 987199 = 987230
37 + 987193 = 987230
103 + 987127 = 987230
151 + 987079 = 987230
163 + 987067 = 987230
241 + 986989 = 987230

Showing the first eight; more decompositions exist.
