Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480396, here are decompositions:

5 + 31480391 = 31480396
23 + 31480373 = 31480396
29 + 31480367 = 31480396
47 + 31480349 = 31480396
107 + 31480289 = 31480396
137 + 31480259 = 31480396
293 + 31480103 = 31480396
317 + 31480079 = 31480396

Showing the first eight; more decompositions exist.
