Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987222, here are decompositions:

11 + 987211 = 987222
13 + 987209 = 987222
23 + 987199 = 987222
29 + 987193 = 987222
31 + 987191 = 987222
79 + 987143 = 987222
139 + 987083 = 987222
179 + 987043 = 987222

Showing the first eight; more decompositions exist.
