Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991708, here are decompositions:

5 + 991703 = 991708
89 + 991619 = 991708
101 + 991607 = 991708
167 + 991541 = 991708
197 + 991511 = 991708
281 + 991427 = 991708
479 + 991229 = 991708
491 + 991217 = 991708

Showing the first eight; more decompositions exist.
