Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549798, here are decompositions:

31 + 549767 = 549798
47 + 549751 = 549798
59 + 549739 = 549798
61 + 549737 = 549798
79 + 549719 = 549798
97 + 549701 = 549798
107 + 549691 = 549798
131 + 549667 = 549798

Showing the first eight; more decompositions exist.
