Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462986, here are decompositions:

7 + 31462979 = 31462986
17 + 31462969 = 31462986
53 + 31462933 = 31462986
89 + 31462897 = 31462986
97 + 31462889 = 31462986
109 + 31462877 = 31462986
179 + 31462807 = 31462986
193 + 31462793 = 31462986

Showing the first eight; more decompositions exist.
