Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460838, here are decompositions:

5 + 31460833 = 31460838
7 + 31460831 = 31460838
29 + 31460809 = 31460838
47 + 31460791 = 31460838
109 + 31460729 = 31460838
137 + 31460701 = 31460838
181 + 31460657 = 31460838
191 + 31460647 = 31460838

Showing the first eight; more decompositions exist.
