Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623012, here are decompositions:

53 + 31622959 = 31623012
61 + 31622951 = 31623012
73 + 31622939 = 31623012
79 + 31622933 = 31623012
89 + 31622923 = 31623012
131 + 31622881 = 31623012
149 + 31622863 = 31623012
233 + 31622779 = 31623012

Showing the first eight; more decompositions exist.
