Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549342, here are decompositions:

11 + 549331 = 549342
19 + 549323 = 549342
23 + 549319 = 549342
29 + 549313 = 549342
61 + 549281 = 549342
83 + 549259 = 549342
113 + 549229 = 549342
139 + 549203 = 549342

Showing the first eight; more decompositions exist.
