Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548140, here are decompositions:

17 + 548123 = 548140
23 + 548117 = 548140
41 + 548099 = 548140
71 + 548069 = 548140
101 + 548039 = 548140
137 + 548003 = 548140
239 + 547901 = 548140
251 + 547889 = 548140

Showing the first eight; more decompositions exist.
