Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475834, here are decompositions:

7 + 31475827 = 31475834
37 + 31475797 = 31475834
151 + 31475683 = 31475834
157 + 31475677 = 31475834
211 + 31475623 = 31475834
223 + 31475611 = 31475834
433 + 31475401 = 31475834
463 + 31475371 = 31475834

Showing the first eight; more decompositions exist.
