Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516294, here are decompositions:

41 + 31516253 = 31516294
53 + 31516241 = 31516294
137 + 31516157 = 31516294
191 + 31516103 = 31516294
233 + 31516061 = 31516294
353 + 31515941 = 31516294
401 + 31515893 = 31516294
617 + 31515677 = 31516294

Showing the first eight; more decompositions exist.
