Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549488, here are decompositions:

7 + 549481 = 549488
67 + 549421 = 549488
97 + 549391 = 549488
109 + 549379 = 549488
157 + 549331 = 549488
229 + 549259 = 549488
241 + 549247 = 549488
349 + 549139 = 549488

Showing the first eight; more decompositions exist.
