Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987510, here are decompositions:

19 + 987491 = 987510
37 + 987473 = 987510
47 + 987463 = 987510
53 + 987457 = 987510
127 + 987383 = 987510
149 + 987361 = 987510
157 + 987353 = 987510
197 + 987313 = 987510

Showing the first eight; more decompositions exist.
