Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473372, here are decompositions:

13 + 31473359 = 31473372
41 + 31473331 = 31473372
59 + 31473313 = 31473372
89 + 31473283 = 31473372
109 + 31473263 = 31473372
131 + 31473241 = 31473372
163 + 31473209 = 31473372
181 + 31473191 = 31473372

Showing the first eight; more decompositions exist.
