Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623152, here are decompositions:

31 + 31623121 = 31623152
193 + 31622959 = 31623152
229 + 31622923 = 31623152
271 + 31622881 = 31623152
349 + 31622803 = 31623152
373 + 31622779 = 31623152
409 + 31622743 = 31623152
439 + 31622713 = 31623152

Showing the first eight; more decompositions exist.
