Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472352, here are decompositions:

13 + 31472339 = 31472352
59 + 31472293 = 31472352
61 + 31472291 = 31472352
113 + 31472239 = 31472352
151 + 31472201 = 31472352
173 + 31472179 = 31472352
193 + 31472159 = 31472352
199 + 31472153 = 31472352

Showing the first eight; more decompositions exist.
