Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623266, here are decompositions:

43 + 31623223 = 31623266
67 + 31623199 = 31623266
97 + 31623169 = 31623266
307 + 31622959 = 31623266
373 + 31622893 = 31623266
457 + 31622809 = 31623266
463 + 31622803 = 31623266
487 + 31622779 = 31623266

Showing the first eight; more decompositions exist.
