Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987300, here are decompositions:

7 + 987293 = 987300
73 + 987227 = 987300
89 + 987211 = 987300
101 + 987199 = 987300
107 + 987193 = 987300
109 + 987191 = 987300
157 + 987143 = 987300
173 + 987127 = 987300

Showing the first eight; more decompositions exist.
