Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465952, here are decompositions:

61 + 31465891 = 31465952
73 + 31465879 = 31465952
103 + 31465849 = 31465952
151 + 31465801 = 31465952
163 + 31465789 = 31465952
211 + 31465741 = 31465952
241 + 31465711 = 31465952
373 + 31465579 = 31465952

Showing the first eight; more decompositions exist.
