Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466072, here are decompositions:

19 + 31466053 = 31466072
73 + 31465999 = 31466072
181 + 31465891 = 31466072
193 + 31465879 = 31466072
223 + 31465849 = 31466072
241 + 31465831 = 31466072
271 + 31465801 = 31466072
283 + 31465789 = 31466072

Showing the first eight; more decompositions exist.
