Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460980, here are decompositions:

3 + 31460977 = 31460980
29 + 31460951 = 31460980
53 + 31460927 = 31460980
101 + 31460879 = 31460980
107 + 31460873 = 31460980
149 + 31460831 = 31460980
197 + 31460783 = 31460980
251 + 31460729 = 31460980

Showing the first eight; more decompositions exist.
