Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549538, here are decompositions:

5 + 549533 = 549538
29 + 549509 = 549538
89 + 549449 = 549538
107 + 549431 = 549538
257 + 549281 = 549538
281 + 549257 = 549538
317 + 549221 = 549538
389 + 549149 = 549538

Showing the first eight; more decompositions exist.
