Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462902, here are decompositions:

5 + 31462897 = 31462902
13 + 31462889 = 31462902
71 + 31462831 = 31462902
109 + 31462793 = 31462902
131 + 31462771 = 31462902
151 + 31462751 = 31462902
173 + 31462729 = 31462902
179 + 31462723 = 31462902

Showing the first eight; more decompositions exist.
