Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623824, here are decompositions:

3 + 31623821 = 31623824
7 + 31623817 = 31623824
103 + 31623721 = 31623824
157 + 31623667 = 31623824
313 + 31623511 = 31623824
487 + 31623337 = 31623824
601 + 31623223 = 31623824
613 + 31623211 = 31623824

Showing the first eight; more decompositions exist.
