Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623726, here are decompositions:

5 + 31623721 = 31623726
19 + 31623707 = 31623726
23 + 31623703 = 31623726
59 + 31623667 = 31623726
103 + 31623623 = 31623726
109 + 31623617 = 31623726
137 + 31623589 = 31623726
227 + 31623499 = 31623726

Showing the first eight; more decompositions exist.
