Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500186, here are decompositions:

7 + 500179 = 500186
13 + 500173 = 500186
19 + 500167 = 500186
67 + 500119 = 500186
73 + 500113 = 500186
79 + 500107 = 500186
103 + 500083 = 500186
157 + 500029 = 500186

Showing the first eight; more decompositions exist.
