Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466844, here are decompositions:

23 + 31466821 = 31466844
53 + 31466791 = 31466844
113 + 31466731 = 31466844
131 + 31466713 = 31466844
137 + 31466707 = 31466844
151 + 31466693 = 31466844
173 + 31466671 = 31466844
257 + 31466587 = 31466844

Showing the first eight; more decompositions exist.
