Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466342, here are decompositions:

13 + 31466329 = 31466342
79 + 31466263 = 31466342
109 + 31466233 = 31466342
199 + 31466143 = 31466342
223 + 31466119 = 31466342
241 + 31466101 = 31466342
463 + 31465879 = 31466342
541 + 31465801 = 31466342

Showing the first eight; more decompositions exist.
