Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462910, here are decompositions:

13 + 31462897 = 31462910
79 + 31462831 = 31462910
103 + 31462807 = 31462910
139 + 31462771 = 31462910
151 + 31462759 = 31462910
163 + 31462747 = 31462910
181 + 31462729 = 31462910
307 + 31462603 = 31462910

Showing the first eight; more decompositions exist.
