Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476944, here are decompositions:

13 + 31476931 = 31476944
73 + 31476871 = 31476944
97 + 31476847 = 31476944
211 + 31476733 = 31476944
241 + 31476703 = 31476944
313 + 31476631 = 31476944
337 + 31476607 = 31476944
397 + 31476547 = 31476944

Showing the first eight; more decompositions exist.
