Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548212, here are decompositions:

11 + 548201 = 548212
23 + 548189 = 548212
59 + 548153 = 548212
89 + 548123 = 548212
113 + 548099 = 548212
173 + 548039 = 548212
311 + 547901 = 548212
359 + 547853 = 548212

Showing the first eight; more decompositions exist.
