Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465982, here are decompositions:

3 + 31465979 = 31465982
103 + 31465879 = 31465982
151 + 31465831 = 31465982
181 + 31465801 = 31465982
193 + 31465789 = 31465982
241 + 31465741 = 31465982
271 + 31465711 = 31465982
421 + 31465561 = 31465982

Showing the first eight; more decompositions exist.
