Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480976, here are decompositions:

3 + 31480973 = 31480976
13 + 31480963 = 31480976
97 + 31480879 = 31480976
103 + 31480873 = 31480976
127 + 31480849 = 31480976
283 + 31480693 = 31480976
337 + 31480639 = 31480976
607 + 31480369 = 31480976

Showing the first eight; more decompositions exist.
