Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548840, here are decompositions:

3 + 548837 = 548840
7 + 548833 = 548840
13 + 548827 = 548840
79 + 548761 = 548840
163 + 548677 = 548840
211 + 548629 = 548840
283 + 548557 = 548840
307 + 548533 = 548840

Showing the first eight; more decompositions exist.
