Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987708, here are decompositions:

11 + 987697 = 987708
101 + 987607 = 987708
109 + 987599 = 987708
149 + 987559 = 987708
167 + 987541 = 987708
199 + 987509 = 987708
251 + 987457 = 987708
317 + 987391 = 987708

Showing the first eight; more decompositions exist.
