Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623244, here are decompositions:

71 + 31623173 = 31623244
131 + 31623113 = 31623244
197 + 31623047 = 31623244
293 + 31622951 = 31623244
311 + 31622933 = 31623244
467 + 31622777 = 31623244
503 + 31622741 = 31623244
557 + 31622687 = 31623244

Showing the first eight; more decompositions exist.
