Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466012, here are decompositions:

13 + 31465999 = 31466012
163 + 31465849 = 31466012
181 + 31465831 = 31466012
211 + 31465801 = 31466012
223 + 31465789 = 31466012
271 + 31465741 = 31466012
349 + 31465663 = 31466012
433 + 31465579 = 31466012

Showing the first eight; more decompositions exist.
