Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548660, here are decompositions:

3 + 548657 = 548660
31 + 548629 = 548660
37 + 548623 = 548660
103 + 548557 = 548660
127 + 548533 = 548660
139 + 548521 = 548660
157 + 548503 = 548660
199 + 548461 = 548660

Showing the first eight; more decompositions exist.
