Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466120, here are decompositions:

13 + 31466107 = 31466120
19 + 31466101 = 31466120
31 + 31466089 = 31466120
67 + 31466053 = 31466120
229 + 31465891 = 31466120
241 + 31465879 = 31466120
271 + 31465849 = 31466120
331 + 31465789 = 31466120

Showing the first eight; more decompositions exist.
