Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987560, here are decompositions:

19 + 987541 = 987560
37 + 987523 = 987560
97 + 987463 = 987560
103 + 987457 = 987560
127 + 987433 = 987560
199 + 987361 = 987560
349 + 987211 = 987560
367 + 987193 = 987560

Showing the first eight; more decompositions exist.
