Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501074, here are decompositions:

13 + 31501061 = 31501074
37 + 31501037 = 31501074
97 + 31500977 = 31501074
107 + 31500967 = 31501074
127 + 31500947 = 31501074
151 + 31500923 = 31501074
211 + 31500863 = 31501074
257 + 31500817 = 31501074

Showing the first eight; more decompositions exist.
