Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623050, here are decompositions:

3 + 31623047 = 31623050
103 + 31622947 = 31623050
127 + 31622923 = 31623050
157 + 31622893 = 31623050
241 + 31622809 = 31623050
271 + 31622779 = 31623050
307 + 31622743 = 31623050
337 + 31622713 = 31623050

Showing the first eight; more decompositions exist.
