Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987368, here are decompositions:

7 + 987361 = 987368
157 + 987211 = 987368
241 + 987127 = 987368
271 + 987097 = 987368
307 + 987061 = 987368
379 + 986989 = 987368
409 + 986959 = 987368
439 + 986929 = 987368

Showing the first eight; more decompositions exist.
