Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515034, here are decompositions:

11 + 31515023 = 31515034
53 + 31514981 = 31515034
71 + 31514963 = 31515034
101 + 31514933 = 31515034
197 + 31514837 = 31515034
251 + 31514783 = 31515034
263 + 31514771 = 31515034
293 + 31514741 = 31515034

Showing the first eight; more decompositions exist.
