Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501128, here are decompositions:

7 + 501121 = 501128
97 + 501031 = 501128
109 + 501019 = 501128
127 + 501001 = 501128
151 + 500977 = 501128
181 + 500947 = 501128
241 + 500887 = 501128
337 + 500791 = 501128

Showing the first eight; more decompositions exist.
