Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466680, here are decompositions:

23 + 31466657 = 31466680
53 + 31466627 = 31466680
83 + 31466597 = 31466680
131 + 31466549 = 31466680
293 + 31466387 = 31466680
353 + 31466327 = 31466680
389 + 31466291 = 31466680
431 + 31466249 = 31466680

Showing the first eight; more decompositions exist.
