Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466700, here are decompositions:

7 + 31466693 = 31466700
11 + 31466689 = 31466700
29 + 31466671 = 31466700
43 + 31466657 = 31466700
71 + 31466629 = 31466700
73 + 31466627 = 31466700
103 + 31466597 = 31466700
113 + 31466587 = 31466700

Showing the first eight; more decompositions exist.
