Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548228, here are decompositions:

7 + 548221 = 548228
139 + 548089 = 548228
229 + 547999 = 548228
271 + 547957 = 548228
277 + 547951 = 548228
379 + 547849 = 548228
397 + 547831 = 548228
409 + 547819 = 548228

Showing the first eight; more decompositions exist.
