Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987884, here are decompositions:

277 + 987607 = 987884
421 + 987463 = 987884
523 + 987361 = 987884
571 + 987313 = 987884
673 + 987211 = 987884
691 + 987193 = 987884
757 + 987127 = 987884
787 + 987097 = 987884

Showing the first eight; more decompositions exist.
