Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466772, here are decompositions:

13 + 31466759 = 31466772
19 + 31466753 = 31466772
23 + 31466749 = 31466772
41 + 31466731 = 31466772
53 + 31466719 = 31466772
59 + 31466713 = 31466772
79 + 31466693 = 31466772
83 + 31466689 = 31466772

Showing the first eight; more decompositions exist.
