Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 983986, here are decompositions:

137 + 983849 = 983986
167 + 983819 = 983986
173 + 983813 = 983986
197 + 983789 = 983986
389 + 983597 = 983986
467 + 983519 = 983986
557 + 983429 = 983986
659 + 983327 = 983986

Showing the first eight; more decompositions exist.
