Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546700, here are decompositions:

37 + 31546663 = 31546700
43 + 31546657 = 31546700
67 + 31546633 = 31546700
79 + 31546621 = 31546700
103 + 31546597 = 31546700
109 + 31546591 = 31546700
127 + 31546573 = 31546700
307 + 31546393 = 31546700

Showing the first eight; more decompositions exist.
