Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623976, here are decompositions:

5 + 31623971 = 31623976
17 + 31623959 = 31623976
23 + 31623953 = 31623976
29 + 31623947 = 31623976
47 + 31623929 = 31623976
89 + 31623887 = 31623976
179 + 31623797 = 31623976
269 + 31623707 = 31623976

Showing the first eight; more decompositions exist.
