Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987512, here are decompositions:

3 + 987509 = 987512
79 + 987433 = 987512
151 + 987361 = 987512
199 + 987313 = 987512
313 + 987199 = 987512
433 + 987079 = 987512
499 + 987013 = 987512
523 + 986989 = 987512

Showing the first eight; more decompositions exist.
