Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474916, here are decompositions:

43 + 31474873 = 31474916
139 + 31474777 = 31474916
223 + 31474693 = 31474916
229 + 31474687 = 31474916
367 + 31474549 = 31474916
397 + 31474519 = 31474916
787 + 31474129 = 31474916
859 + 31474057 = 31474916

Showing the first eight; more decompositions exist.
