Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466732, here are decompositions:

13 + 31466719 = 31466732
19 + 31466713 = 31466732
43 + 31466689 = 31466732
61 + 31466671 = 31466732
103 + 31466629 = 31466732
229 + 31466503 = 31466732
331 + 31466401 = 31466732
499 + 31466233 = 31466732

Showing the first eight; more decompositions exist.
