Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548990, here are decompositions:

37 + 548953 = 548990
97 + 548893 = 548990
139 + 548851 = 548990
157 + 548833 = 548990
163 + 548827 = 548990
199 + 548791 = 548990
229 + 548761 = 548990
241 + 548749 = 548990

Showing the first eight; more decompositions exist.
