Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480882, here are decompositions:

3 + 31480879 = 31480882
53 + 31480829 = 31480882
89 + 31480793 = 31480882
113 + 31480769 = 31480882
149 + 31480733 = 31480882
233 + 31480649 = 31480882
353 + 31480529 = 31480882
449 + 31480433 = 31480882

Showing the first eight; more decompositions exist.
