Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480766, here are decompositions:

3 + 31480763 = 31480766
73 + 31480693 = 31480766
127 + 31480639 = 31480766
397 + 31480369 = 31480766
937 + 31479829 = 31480766
997 + 31479769 = 31480766
1009 + 31479757 = 31480766
1069 + 31479697 = 31480766

Showing the first eight; more decompositions exist.
