Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472304, here are decompositions:

11 + 31472293 = 31472304
13 + 31472291 = 31472304
43 + 31472261 = 31472304
103 + 31472201 = 31472304
113 + 31472191 = 31472304
137 + 31472167 = 31472304
151 + 31472153 = 31472304
173 + 31472131 = 31472304

Showing the first eight; more decompositions exist.
