Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447376, here are decompositions:

13 + 31447363 = 31447376
19 + 31447357 = 31447376
43 + 31447333 = 31447376
109 + 31447267 = 31447376
277 + 31447099 = 31447376
307 + 31447069 = 31447376
349 + 31447027 = 31447376
379 + 31446997 = 31447376

Showing the first eight; more decompositions exist.
