Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480866, here are decompositions:

5 + 31480861 = 31480866
17 + 31480849 = 31480866
37 + 31480829 = 31480866
73 + 31480793 = 31480866
97 + 31480769 = 31480866
103 + 31480763 = 31480866
173 + 31480693 = 31480866
227 + 31480639 = 31480866

Showing the first eight; more decompositions exist.
