Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545128, here are decompositions:

11 + 545117 = 545128
41 + 545087 = 545128
71 + 545057 = 545128
149 + 544979 = 545128
167 + 544961 = 545128
191 + 544937 = 545128
239 + 544889 = 545128
251 + 544877 = 545128

Showing the first eight; more decompositions exist.
