Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468074, here are decompositions:

7 + 31468067 = 31468074
47 + 31468027 = 31468074
61 + 31468013 = 31468074
73 + 31468001 = 31468074
107 + 31467967 = 31468074
137 + 31467937 = 31468074
163 + 31467911 = 31468074
181 + 31467893 = 31468074

Showing the first eight; more decompositions exist.
