Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987576, here are decompositions:

17 + 987559 = 987576
43 + 987533 = 987576
53 + 987523 = 987576
67 + 987509 = 987576
103 + 987473 = 987576
113 + 987463 = 987576
193 + 987383 = 987576
223 + 987353 = 987576

Showing the first eight; more decompositions exist.
