Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987534, here are decompositions:

11 + 987523 = 987534
43 + 987491 = 987534
61 + 987473 = 987534
71 + 987463 = 987534
101 + 987433 = 987534
151 + 987383 = 987534
173 + 987361 = 987534
181 + 987353 = 987534

Showing the first eight; more decompositions exist.
