Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623960, here are decompositions:

7 + 31623953 = 31623960
13 + 31623947 = 31623960
29 + 31623931 = 31623960
31 + 31623929 = 31623960
59 + 31623901 = 31623960
73 + 31623887 = 31623960
103 + 31623857 = 31623960
139 + 31623821 = 31623960

Showing the first eight; more decompositions exist.
