Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623952, here are decompositions:

5 + 31623947 = 31623952
23 + 31623929 = 31623952
131 + 31623821 = 31623952
251 + 31623701 = 31623952
281 + 31623671 = 31623952
431 + 31623521 = 31623952
443 + 31623509 = 31623952
461 + 31623491 = 31623952

Showing the first eight; more decompositions exist.
