Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532836, here are decompositions:

3 + 31532833 = 31532836
59 + 31532777 = 31532836
149 + 31532687 = 31532836
197 + 31532639 = 31532836
239 + 31532597 = 31532836
263 + 31532573 = 31532836
347 + 31532489 = 31532836
359 + 31532477 = 31532836

Showing the first eight; more decompositions exist.
