Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460982, here are decompositions:

5 + 31460977 = 31460982
11 + 31460971 = 31460982
31 + 31460951 = 31460982
53 + 31460929 = 31460982
103 + 31460879 = 31460982
109 + 31460873 = 31460982
131 + 31460851 = 31460982
149 + 31460833 = 31460982

Showing the first eight; more decompositions exist.
