Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451058, here are decompositions:

11 + 31451047 = 31451058
29 + 31451029 = 31451058
61 + 31450997 = 31451058
97 + 31450961 = 31451058
109 + 31450949 = 31451058
167 + 31450891 = 31451058
179 + 31450879 = 31451058
211 + 31450847 = 31451058

Showing the first eight; more decompositions exist.
