Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516354, here are decompositions:

101 + 31516253 = 31516354
113 + 31516241 = 31516354
197 + 31516157 = 31516354
251 + 31516103 = 31516354
293 + 31516061 = 31516354
347 + 31516007 = 31516354
461 + 31515893 = 31516354
587 + 31515767 = 31516354

Showing the first eight; more decompositions exist.
