Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501156, here are decompositions:

17 + 501139 = 501156
23 + 501133 = 501156
53 + 501103 = 501156
67 + 501089 = 501156
79 + 501077 = 501156
113 + 501043 = 501156
127 + 501029 = 501156
137 + 501019 = 501156

Showing the first eight; more decompositions exist.
