Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987212, here are decompositions:

3 + 987209 = 987212
13 + 987199 = 987212
19 + 987193 = 987212
151 + 987061 = 987212
199 + 987013 = 987212
223 + 986989 = 987212
229 + 986983 = 987212
271 + 986941 = 987212

Showing the first eight; more decompositions exist.
