Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987504, here are decompositions:

13 + 987491 = 987504
31 + 987473 = 987504
41 + 987463 = 987504
47 + 987457 = 987504
71 + 987433 = 987504
113 + 987391 = 987504
151 + 987353 = 987504
191 + 987313 = 987504

Showing the first eight; more decompositions exist.
