Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462968, here are decompositions:

37 + 31462931 = 31462968
59 + 31462909 = 31462968
67 + 31462901 = 31462968
71 + 31462897 = 31462968
79 + 31462889 = 31462968
137 + 31462831 = 31462968
157 + 31462811 = 31462968
197 + 31462771 = 31462968

Showing the first eight; more decompositions exist.
