Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623270, here are decompositions:

13 + 31623257 = 31623270
47 + 31623223 = 31623270
59 + 31623211 = 31623270
61 + 31623209 = 31623270
71 + 31623199 = 31623270
89 + 31623181 = 31623270
97 + 31623173 = 31623270
101 + 31623169 = 31623270

Showing the first eight; more decompositions exist.
