Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466912, here are decompositions:

13 + 31466899 = 31466912
19 + 31466893 = 31466912
163 + 31466749 = 31466912
181 + 31466731 = 31466912
193 + 31466719 = 31466912
199 + 31466713 = 31466912
223 + 31466689 = 31466912
241 + 31466671 = 31466912

Showing the first eight; more decompositions exist.
