Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549630, here are decompositions:

7 + 549623 = 549630
23 + 549607 = 549630
41 + 549589 = 549630
43 + 549587 = 549630
61 + 549569 = 549630
79 + 549551 = 549630
83 + 549547 = 549630
97 + 549533 = 549630

Showing the first eight; more decompositions exist.
