Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549728, here are decompositions:

37 + 549691 = 549728
61 + 549667 = 549728
79 + 549649 = 549728
139 + 549589 = 549728
181 + 549547 = 549728
211 + 549517 = 549728
307 + 549421 = 549728
337 + 549391 = 549728

Showing the first eight; more decompositions exist.
