Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460976, here are decompositions:

5 + 31460971 = 31460976
47 + 31460929 = 31460976
59 + 31460917 = 31460976
97 + 31460879 = 31460976
103 + 31460873 = 31460976
137 + 31460839 = 31460976
139 + 31460837 = 31460976
167 + 31460809 = 31460976

Showing the first eight; more decompositions exist.
