Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516492, here are decompositions:

23 + 31516469 = 31516492
113 + 31516379 = 31516492
131 + 31516361 = 31516492
173 + 31516319 = 31516492
239 + 31516253 = 31516492
251 + 31516241 = 31516492
353 + 31516139 = 31516492
383 + 31516109 = 31516492

Showing the first eight; more decompositions exist.
