Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623496, here are decompositions:

5 + 31623491 = 31623496
17 + 31623479 = 31623496
53 + 31623443 = 31623496
239 + 31623257 = 31623496
383 + 31623113 = 31623496
449 + 31623047 = 31623496
557 + 31622939 = 31623496
563 + 31622933 = 31623496

Showing the first eight; more decompositions exist.
