Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446452, here are decompositions:

13 + 31446439 = 31446452
199 + 31446253 = 31446452
211 + 31446241 = 31446452
223 + 31446229 = 31446452
229 + 31446223 = 31446452
241 + 31446211 = 31446452
421 + 31446031 = 31446452
523 + 31445929 = 31446452

Showing the first eight; more decompositions exist.
