Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462980, here are decompositions:

11 + 31462969 = 31462980
47 + 31462933 = 31462980
71 + 31462909 = 31462980
79 + 31462901 = 31462980
83 + 31462897 = 31462980
103 + 31462877 = 31462980
149 + 31462831 = 31462980
173 + 31462807 = 31462980

Showing the first eight; more decompositions exist.
