Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462932, here are decompositions:

23 + 31462909 = 31462932
31 + 31462901 = 31462932
43 + 31462889 = 31462932
101 + 31462831 = 31462932
139 + 31462793 = 31462932
173 + 31462759 = 31462932
181 + 31462751 = 31462932
283 + 31462649 = 31462932

Showing the first eight; more decompositions exist.
