Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473166, here are decompositions:

3 + 31473163 = 31473166
5 + 31473161 = 31473166
59 + 31473107 = 31473166
83 + 31473083 = 31473166
89 + 31473077 = 31473166
239 + 31472927 = 31473166
317 + 31472849 = 31473166
353 + 31472813 = 31473166

Showing the first eight; more decompositions exist.
