Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623958, here are decompositions:

5 + 31623953 = 31623958
11 + 31623947 = 31623958
29 + 31623929 = 31623958
71 + 31623887 = 31623958
101 + 31623857 = 31623958
137 + 31623821 = 31623958
227 + 31623731 = 31623958
251 + 31623707 = 31623958

Showing the first eight; more decompositions exist.
