Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623332, here are decompositions:

109 + 31623223 = 31623332
151 + 31623181 = 31623332
163 + 31623169 = 31623332
211 + 31623121 = 31623332
271 + 31623061 = 31623332
373 + 31622959 = 31623332
409 + 31622923 = 31623332
439 + 31622893 = 31623332

Showing the first eight; more decompositions exist.
