Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463952, here are decompositions:

11 + 31463941 = 31463952
31 + 31463921 = 31463952
41 + 31463911 = 31463952
43 + 31463909 = 31463952
59 + 31463893 = 31463952
61 + 31463891 = 31463952
73 + 31463879 = 31463952
103 + 31463849 = 31463952

Showing the first eight; more decompositions exist.
