Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987914, here are decompositions:

3 + 987911 = 987914
283 + 987631 = 987914
307 + 987607 = 987914
373 + 987541 = 987914
457 + 987457 = 987914
523 + 987391 = 987914
601 + 987313 = 987914
787 + 987127 = 987914

Showing the first eight; more decompositions exist.
