Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549850, here are decompositions:

11 + 549839 = 549850
17 + 549833 = 549850
83 + 549767 = 549850
101 + 549749 = 549850
113 + 549737 = 549850
131 + 549719 = 549850
137 + 549713 = 549850
149 + 549701 = 549850

Showing the first eight; more decompositions exist.
