Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623118, here are decompositions:

5 + 31623113 = 31623118
71 + 31623047 = 31623118
167 + 31622951 = 31623118
179 + 31622939 = 31623118
281 + 31622837 = 31623118
389 + 31622729 = 31623118
419 + 31622699 = 31623118
431 + 31622687 = 31623118

Showing the first eight; more decompositions exist.
