Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548180, here are decompositions:

37 + 548143 = 548180
97 + 548083 = 548180
181 + 547999 = 548180
223 + 547957 = 548180
229 + 547951 = 548180
271 + 547909 = 548180
331 + 547849 = 548180
349 + 547831 = 548180

Showing the first eight; more decompositions exist.
