Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987372, here are decompositions:

11 + 987361 = 987372
19 + 987353 = 987372
59 + 987313 = 987372
73 + 987299 = 987372
79 + 987293 = 987372
163 + 987209 = 987372
173 + 987199 = 987372
179 + 987193 = 987372

Showing the first eight; more decompositions exist.
