Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451046, here are decompositions:

13 + 31451033 = 31451046
17 + 31451029 = 31451046
79 + 31450967 = 31451046
97 + 31450949 = 31451046
149 + 31450897 = 31451046
167 + 31450879 = 31451046
199 + 31450847 = 31451046
223 + 31450823 = 31451046

Showing the first eight; more decompositions exist.
