Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505094, here are decompositions:

13 + 31505081 = 31505094
17 + 31505077 = 31505094
67 + 31505027 = 31505094
107 + 31504987 = 31505094
113 + 31504981 = 31505094
151 + 31504943 = 31505094
191 + 31504903 = 31505094
211 + 31504883 = 31505094

Showing the first eight; more decompositions exist.
