Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516348, here are decompositions:

29 + 31516319 = 31516348
107 + 31516241 = 31516348
191 + 31516157 = 31516348
239 + 31516109 = 31516348
359 + 31515989 = 31516348
449 + 31515899 = 31516348
467 + 31515881 = 31516348
491 + 31515857 = 31516348

Showing the first eight; more decompositions exist.
