Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549420, here are decompositions:

17 + 549403 = 549420
29 + 549391 = 549420
41 + 549379 = 549420
89 + 549331 = 549420
97 + 549323 = 549420
101 + 549319 = 549420
107 + 549313 = 549420
139 + 549281 = 549420

Showing the first eight; more decompositions exist.
