Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473696, here are decompositions:

97 + 31473599 = 31473696
103 + 31473593 = 31473696
113 + 31473583 = 31473696
167 + 31473529 = 31473696
173 + 31473523 = 31473696
239 + 31473457 = 31473696
283 + 31473413 = 31473696
337 + 31473359 = 31473696

Showing the first eight; more decompositions exist.
