Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987330, here are decompositions:

17 + 987313 = 987330
31 + 987299 = 987330
37 + 987293 = 987330
79 + 987251 = 987330
103 + 987227 = 987330
131 + 987199 = 987330
137 + 987193 = 987330
139 + 987191 = 987330

Showing the first eight; more decompositions exist.
