Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494466, here are decompositions:

23 + 31494443 = 31494466
173 + 31494293 = 31494466
347 + 31494119 = 31494466
383 + 31494083 = 31494466
467 + 31493999 = 31494466
557 + 31493909 = 31494466
677 + 31493789 = 31494466
683 + 31493783 = 31494466

Showing the first eight; more decompositions exist.
