Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473966, here are decompositions:

59 + 31473907 = 31473966
79 + 31473887 = 31473966
103 + 31473863 = 31473966
127 + 31473839 = 31473966
157 + 31473809 = 31473966
233 + 31473733 = 31473966
263 + 31473703 = 31473966
367 + 31473599 = 31473966

Showing the first eight; more decompositions exist.
