Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623044, here are decompositions:

3 + 31623041 = 31623044
97 + 31622947 = 31623044
151 + 31622893 = 31623044
163 + 31622881 = 31623044
181 + 31622863 = 31623044
241 + 31622803 = 31623044
331 + 31622713 = 31623044
373 + 31622671 = 31623044

Showing the first eight; more decompositions exist.
