Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623996, here are decompositions:

7 + 31623989 = 31623996
13 + 31623983 = 31623996
17 + 31623979 = 31623996
29 + 31623967 = 31623996
37 + 31623959 = 31623996
43 + 31623953 = 31623996
67 + 31623929 = 31623996
109 + 31623887 = 31623996

Showing the first eight; more decompositions exist.
