Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623910, here are decompositions:

23 + 31623887 = 31623910
53 + 31623857 = 31623910
89 + 31623821 = 31623910
113 + 31623797 = 31623910
179 + 31623731 = 31623910
239 + 31623671 = 31623910
293 + 31623617 = 31623910
389 + 31623521 = 31623910

Showing the first eight; more decompositions exist.
