Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549906, here are decompositions:

23 + 549883 = 549906
29 + 549877 = 549906
43 + 549863 = 549906
67 + 549839 = 549906
73 + 549833 = 549906
89 + 549817 = 549906
139 + 549767 = 549906
157 + 549749 = 549906

Showing the first eight; more decompositions exist.
