Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548028, here are decompositions:

29 + 547999 = 548028
71 + 547957 = 548028
127 + 547901 = 548028
139 + 547889 = 548028
157 + 547871 = 548028
179 + 547849 = 548028
197 + 547831 = 548028
211 + 547817 = 548028

Showing the first eight; more decompositions exist.
