Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460964, here are decompositions:

13 + 31460951 = 31460964
37 + 31460927 = 31460964
47 + 31460917 = 31460964
113 + 31460851 = 31460964
127 + 31460837 = 31460964
131 + 31460833 = 31460964
173 + 31460791 = 31460964
181 + 31460783 = 31460964

Showing the first eight; more decompositions exist.
