Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987516, here are decompositions:

7 + 987509 = 987516
43 + 987473 = 987516
53 + 987463 = 987516
59 + 987457 = 987516
83 + 987433 = 987516
163 + 987353 = 987516
223 + 987293 = 987516
307 + 987209 = 987516

Showing the first eight; more decompositions exist.
