Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987566, here are decompositions:

7 + 987559 = 987566
43 + 987523 = 987566
103 + 987463 = 987566
109 + 987457 = 987566
367 + 987199 = 987566
373 + 987193 = 987566
439 + 987127 = 987566
487 + 987079 = 987566

Showing the first eight; more decompositions exist.
