Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620452, here are decompositions:

43 + 31620409 = 31620452
109 + 31620343 = 31620452
151 + 31620301 = 31620452
223 + 31620229 = 31620452
229 + 31620223 = 31620452
313 + 31620139 = 31620452
433 + 31620019 = 31620452
439 + 31620013 = 31620452

Showing the first eight; more decompositions exist.
