Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466802, here are decompositions:

11 + 31466791 = 31466802
43 + 31466759 = 31466802
53 + 31466749 = 31466802
71 + 31466731 = 31466802
83 + 31466719 = 31466802
89 + 31466713 = 31466802
109 + 31466693 = 31466802
113 + 31466689 = 31466802

Showing the first eight; more decompositions exist.
