Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623966, here are decompositions:

7 + 31623959 = 31623966
13 + 31623953 = 31623966
19 + 31623947 = 31623966
37 + 31623929 = 31623966
79 + 31623887 = 31623966
109 + 31623857 = 31623966
149 + 31623817 = 31623966
263 + 31623703 = 31623966

Showing the first eight; more decompositions exist.
