Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623982, here are decompositions:

3 + 31623979 = 31623982
11 + 31623971 = 31623982
23 + 31623959 = 31623982
29 + 31623953 = 31623982
53 + 31623929 = 31623982
251 + 31623731 = 31623982
281 + 31623701 = 31623982
311 + 31623671 = 31623982

Showing the first eight; more decompositions exist.
