Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500180, here are decompositions:

3 + 500177 = 500180
7 + 500173 = 500180
13 + 500167 = 500180
61 + 500119 = 500180
67 + 500113 = 500180
73 + 500107 = 500180
97 + 500083 = 500180
139 + 500041 = 500180

Showing the first eight; more decompositions exist.
