Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472350, here are decompositions:

11 + 31472339 = 31472350
59 + 31472291 = 31472350
89 + 31472261 = 31472350
149 + 31472201 = 31472350
167 + 31472183 = 31472350
191 + 31472159 = 31472350
197 + 31472153 = 31472350
227 + 31472123 = 31472350

Showing the first eight; more decompositions exist.
