Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504068, here are decompositions:

17 + 31504051 = 31504068
31 + 31504037 = 31504068
97 + 31503971 = 31504068
107 + 31503961 = 31504068
137 + 31503931 = 31504068
139 + 31503929 = 31504068
151 + 31503917 = 31504068
157 + 31503911 = 31504068

Showing the first eight; more decompositions exist.
