Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460958, here are decompositions:

7 + 31460951 = 31460958
29 + 31460929 = 31460958
31 + 31460927 = 31460958
41 + 31460917 = 31460958
79 + 31460879 = 31460958
107 + 31460851 = 31460958
127 + 31460831 = 31460958
149 + 31460809 = 31460958

Showing the first eight; more decompositions exist.
