Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987340, here are decompositions:

41 + 987299 = 987340
47 + 987293 = 987340
89 + 987251 = 987340
113 + 987227 = 987340
131 + 987209 = 987340
149 + 987191 = 987340
197 + 987143 = 987340
239 + 987101 = 987340

Showing the first eight; more decompositions exist.
