Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500172, here are decompositions:

5 + 500167 = 500172
19 + 500153 = 500172
53 + 500119 = 500172
59 + 500113 = 500172
61 + 500111 = 500172
89 + 500083 = 500172
103 + 500069 = 500172
131 + 500041 = 500172

Showing the first eight; more decompositions exist.
