Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480096, here are decompositions:

5 + 31480091 = 31480096
17 + 31480079 = 31480096
47 + 31480049 = 31480096
149 + 31479947 = 31480096
239 + 31479857 = 31480096
293 + 31479803 = 31480096
353 + 31479743 = 31480096
359 + 31479737 = 31480096

Showing the first eight; more decompositions exist.
