Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549740, here are decompositions:

3 + 549737 = 549740
7 + 549733 = 549740
73 + 549667 = 549740
97 + 549643 = 549740
151 + 549589 = 549740
193 + 549547 = 549740
223 + 549517 = 549740
229 + 549511 = 549740

Showing the first eight; more decompositions exist.
