Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472, here are decompositions:

3 + 31469 = 31472
79 + 31393 = 31472
139 + 31333 = 31472
151 + 31321 = 31472
223 + 31249 = 31472
241 + 31231 = 31472
283 + 31189 = 31472
313 + 31159 = 31472

Showing the first eight; more decompositions exist.
