Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623994, here are decompositions:

5 + 31623989 = 31623994
11 + 31623983 = 31623994
23 + 31623971 = 31623994
41 + 31623953 = 31623994
47 + 31623947 = 31623994
107 + 31623887 = 31623994
137 + 31623857 = 31623994
173 + 31623821 = 31623994

Showing the first eight; more decompositions exist.
