Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623452, here are decompositions:

13 + 31623439 = 31623452
31 + 31623421 = 31623452
79 + 31623373 = 31623452
109 + 31623343 = 31623452
229 + 31623223 = 31623452
241 + 31623211 = 31623452
271 + 31623181 = 31623452
283 + 31623169 = 31623452

Showing the first eight; more decompositions exist.
