Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462970, here are decompositions:

37 + 31462933 = 31462970
61 + 31462909 = 31462970
73 + 31462897 = 31462970
139 + 31462831 = 31462970
163 + 31462807 = 31462970
199 + 31462771 = 31462970
211 + 31462759 = 31462970
223 + 31462747 = 31462970

Showing the first eight; more decompositions exist.
