Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475360, here are decompositions:

19 + 31475341 = 31475360
43 + 31475317 = 31475360
73 + 31475287 = 31475360
109 + 31475251 = 31475360
151 + 31475209 = 31475360
229 + 31475131 = 31475360
271 + 31475089 = 31475360
277 + 31475083 = 31475360

Showing the first eight; more decompositions exist.
