Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549330, here are decompositions:

7 + 549323 = 549330
11 + 549319 = 549330
17 + 549313 = 549330
71 + 549259 = 549330
73 + 549257 = 549330
83 + 549247 = 549330
101 + 549229 = 549330
109 + 549221 = 549330

Showing the first eight; more decompositions exist.
