Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548666, here are decompositions:

37 + 548629 = 548666
43 + 548623 = 548666
109 + 548557 = 548666
163 + 548503 = 548666
439 + 548227 = 548666
523 + 548143 = 548666
577 + 548089 = 548666
607 + 548059 = 548666

Showing the first eight; more decompositions exist.
