Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550686, here are decompositions:

7 + 550679 = 550686
23 + 550663 = 550686
29 + 550657 = 550686
79 + 550607 = 550686
109 + 550577 = 550686
167 + 550519 = 550686
173 + 550513 = 550686
197 + 550489 = 550686

Showing the first eight; more decompositions exist.
