Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559704, here are decompositions:

5 + 31559699 = 31559704
17 + 31559687 = 31559704
23 + 31559681 = 31559704
53 + 31559651 = 31559704
131 + 31559573 = 31559704
167 + 31559537 = 31559704
233 + 31559471 = 31559704
257 + 31559447 = 31559704

Showing the first eight; more decompositions exist.
