Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447310, here are decompositions:

43 + 31447267 = 31447310
211 + 31447099 = 31447310
229 + 31447081 = 31447310
241 + 31447069 = 31447310
283 + 31447027 = 31447310
313 + 31446997 = 31447310
337 + 31446973 = 31447310
373 + 31446937 = 31447310

Showing the first eight; more decompositions exist.
