Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482616, here are decompositions:

3 + 31482613 = 31482616
17 + 31482599 = 31482616
29 + 31482587 = 31482616
47 + 31482569 = 31482616
107 + 31482509 = 31482616
227 + 31482389 = 31482616
359 + 31482257 = 31482616
443 + 31482173 = 31482616

Showing the first eight; more decompositions exist.
