Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466718, here are decompositions:

5 + 31466713 = 31466718
11 + 31466707 = 31466718
29 + 31466689 = 31466718
47 + 31466671 = 31466718
61 + 31466657 = 31466718
89 + 31466629 = 31466718
131 + 31466587 = 31466718
317 + 31466401 = 31466718

Showing the first eight; more decompositions exist.
