Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466892, here are decompositions:

19 + 31466873 = 31466892
43 + 31466849 = 31466892
71 + 31466821 = 31466892
101 + 31466791 = 31466892
139 + 31466753 = 31466892
173 + 31466719 = 31466892
179 + 31466713 = 31466892
199 + 31466693 = 31466892

Showing the first eight; more decompositions exist.
