Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447334, here are decompositions:

67 + 31447267 = 31447334
307 + 31447027 = 31447334
313 + 31447021 = 31447334
337 + 31446997 = 31447334
397 + 31446937 = 31447334
463 + 31446871 = 31447334
487 + 31446847 = 31447334
577 + 31446757 = 31447334

Showing the first eight; more decompositions exist.
