Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466410, here are decompositions:

23 + 31466387 = 31466410
29 + 31466381 = 31466410
83 + 31466327 = 31466410
347 + 31466063 = 31466410
359 + 31466051 = 31466410
431 + 31465979 = 31466410
653 + 31465757 = 31466410
683 + 31465727 = 31466410

Showing the first eight; more decompositions exist.
