Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452006, here are decompositions:

7 + 31451999 = 31452006
13 + 31451993 = 31452006
37 + 31451969 = 31452006
97 + 31451909 = 31452006
137 + 31451869 = 31452006
149 + 31451857 = 31452006
167 + 31451839 = 31452006
199 + 31451807 = 31452006

Showing the first eight; more decompositions exist.
