Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549382, here are decompositions:

3 + 549379 = 549382
59 + 549323 = 549382
101 + 549281 = 549382
179 + 549203 = 549382
233 + 549149 = 549382
293 + 549089 = 549382
311 + 549071 = 549382
359 + 549023 = 549382

Showing the first eight; more decompositions exist.
