Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623954, here are decompositions:

7 + 31623947 = 31623954
23 + 31623931 = 31623954
53 + 31623901 = 31623954
67 + 31623887 = 31623954
97 + 31623857 = 31623954
137 + 31623817 = 31623954
157 + 31623797 = 31623954
223 + 31623731 = 31623954

Showing the first eight; more decompositions exist.
