Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620252, here are decompositions:

23 + 31620229 = 31620252
29 + 31620223 = 31620252
43 + 31620209 = 31620252
61 + 31620191 = 31620252
101 + 31620151 = 31620252
113 + 31620139 = 31620252
193 + 31620059 = 31620252
233 + 31620019 = 31620252

Showing the first eight; more decompositions exist.
