Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549690, here are decompositions:

7 + 549683 = 549690
23 + 549667 = 549690
41 + 549649 = 549690
47 + 549643 = 549690
67 + 549623 = 549690
83 + 549607 = 549690
101 + 549589 = 549690
103 + 549587 = 549690

Showing the first eight; more decompositions exist.
