Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549942, here are decompositions:

5 + 549937 = 549942
31 + 549911 = 549942
59 + 549883 = 549942
79 + 549863 = 549942
103 + 549839 = 549942
109 + 549833 = 549942
191 + 549751 = 549942
193 + 549749 = 549942

Showing the first eight; more decompositions exist.
