Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549986, here are decompositions:

7 + 549979 = 549986
37 + 549949 = 549986
43 + 549943 = 549986
103 + 549883 = 549986
109 + 549877 = 549986
337 + 549649 = 549986
379 + 549607 = 549986
397 + 549589 = 549986

Showing the first eight; more decompositions exist.
