Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466816, here are decompositions:

67 + 31466749 = 31466816
97 + 31466719 = 31466816
103 + 31466713 = 31466816
109 + 31466707 = 31466816
127 + 31466689 = 31466816
229 + 31466587 = 31466816
313 + 31466503 = 31466816
487 + 31466329 = 31466816

Showing the first eight; more decompositions exist.
