Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462962, here are decompositions:

29 + 31462933 = 31462962
31 + 31462931 = 31462962
53 + 31462909 = 31462962
61 + 31462901 = 31462962
73 + 31462889 = 31462962
131 + 31462831 = 31462962
151 + 31462811 = 31462962
191 + 31462771 = 31462962

Showing the first eight; more decompositions exist.
