Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623382, here are decompositions:

5 + 31623377 = 31623382
173 + 31623209 = 31623382
269 + 31623113 = 31623382
359 + 31623023 = 31623382
431 + 31622951 = 31623382
443 + 31622939 = 31623382
449 + 31622933 = 31623382
641 + 31622741 = 31623382

Showing the first eight; more decompositions exist.
