Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515076, here are decompositions:

3 + 31515073 = 31515076
29 + 31515047 = 31515076
53 + 31515023 = 31515076
107 + 31514969 = 31515076
113 + 31514963 = 31515076
227 + 31514849 = 31515076
239 + 31514837 = 31515076
293 + 31514783 = 31515076

Showing the first eight; more decompositions exist.
