Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501018, here are decompositions:

5 + 501013 = 501018
17 + 501001 = 501018
41 + 500977 = 501018
61 + 500957 = 501018
71 + 500947 = 501018
97 + 500921 = 501018
107 + 500911 = 501018
109 + 500909 = 501018

Showing the first eight; more decompositions exist.
