Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987508, here are decompositions:

17 + 987491 = 987508
257 + 987251 = 987508
281 + 987227 = 987508
317 + 987191 = 987508
419 + 987089 = 987508
479 + 987029 = 987508
659 + 986849 = 987508
911 + 986597 = 987508

Showing the first eight; more decompositions exist.
