Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987288, here are decompositions:

37 + 987251 = 987288
61 + 987227 = 987288
79 + 987209 = 987288
89 + 987199 = 987288
97 + 987191 = 987288
191 + 987097 = 987288
199 + 987089 = 987288
227 + 987061 = 987288

Showing the first eight; more decompositions exist.
