Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460666, here are decompositions:

19 + 31460647 = 31460666
157 + 31460509 = 31460666
337 + 31460329 = 31460666
373 + 31460293 = 31460666
499 + 31460167 = 31460666
613 + 31460053 = 31460666
673 + 31459993 = 31460666
859 + 31459807 = 31460666

Showing the first eight; more decompositions exist.
