Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987164, here are decompositions:

37 + 987127 = 987164
67 + 987097 = 987164
97 + 987067 = 987164
103 + 987061 = 987164
151 + 987013 = 987164
181 + 986983 = 987164
223 + 986941 = 987164
307 + 986857 = 987164

Showing the first eight; more decompositions exist.
