Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623416, here are decompositions:

43 + 31623373 = 31623416
73 + 31623343 = 31623416
79 + 31623337 = 31623416
193 + 31623223 = 31623416
457 + 31622959 = 31623416
523 + 31622893 = 31623416
607 + 31622809 = 31623416
613 + 31622803 = 31623416

Showing the first eight; more decompositions exist.
