Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515334, here are decompositions:

17 + 31515317 = 31515334
23 + 31515311 = 31515334
47 + 31515287 = 31515334
107 + 31515227 = 31515334
197 + 31515137 = 31515334
293 + 31515041 = 31515334
311 + 31515023 = 31515334
353 + 31514981 = 31515334

Showing the first eight; more decompositions exist.
