Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515094, here are decompositions:

47 + 31515047 = 31515094
53 + 31515041 = 31515094
71 + 31515023 = 31515094
113 + 31514981 = 31515094
131 + 31514963 = 31515094
257 + 31514837 = 31515094
311 + 31514783 = 31515094
353 + 31514741 = 31515094

Showing the first eight; more decompositions exist.
