Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623526, here are decompositions:

3 + 31623523 = 31623526
5 + 31623521 = 31623526
17 + 31623509 = 31623526
29 + 31623497 = 31623526
47 + 31623479 = 31623526
83 + 31623443 = 31623526
149 + 31623377 = 31623526
269 + 31623257 = 31623526

Showing the first eight; more decompositions exist.
