Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466832, here are decompositions:

11 + 31466821 = 31466832
41 + 31466791 = 31466832
73 + 31466759 = 31466832
79 + 31466753 = 31466832
83 + 31466749 = 31466832
101 + 31466731 = 31466832
113 + 31466719 = 31466832
139 + 31466693 = 31466832

Showing the first eight; more decompositions exist.
