Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549688, here are decompositions:

5 + 549683 = 549688
47 + 549641 = 549688
101 + 549587 = 549688
137 + 549551 = 549688
179 + 549509 = 549688
239 + 549449 = 549688
257 + 549431 = 549688
431 + 549257 = 549688

Showing the first eight; more decompositions exist.
