Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500178, here are decompositions:

5 + 500173 = 500178
11 + 500167 = 500178
59 + 500119 = 500178
67 + 500111 = 500178
71 + 500107 = 500178
109 + 500069 = 500178
137 + 500041 = 500178
149 + 500029 = 500178

Showing the first eight; more decompositions exist.
