Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473946, here are decompositions:

29 + 31473917 = 31473946
59 + 31473887 = 31473946
83 + 31473863 = 31473946
107 + 31473839 = 31473946
137 + 31473809 = 31473946
167 + 31473779 = 31473946
239 + 31473707 = 31473946
347 + 31473599 = 31473946

Showing the first eight; more decompositions exist.
