Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548628, here are decompositions:

5 + 548623 = 548628
37 + 548591 = 548628
61 + 548567 = 548628
71 + 548557 = 548628
107 + 548521 = 548628
109 + 548519 = 548628
127 + 548501 = 548628
139 + 548489 = 548628

Showing the first eight; more decompositions exist.
