Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549890, here are decompositions:

7 + 549883 = 549890
13 + 549877 = 549890
73 + 549817 = 549890
139 + 549751 = 549890
151 + 549739 = 549890
157 + 549733 = 549890
199 + 549691 = 549890
223 + 549667 = 549890

Showing the first eight; more decompositions exist.
