Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532824, here are decompositions:

47 + 31532777 = 31532824
131 + 31532693 = 31532824
137 + 31532687 = 31532824
227 + 31532597 = 31532824
251 + 31532573 = 31532824
317 + 31532507 = 31532824
347 + 31532477 = 31532824
563 + 31532261 = 31532824

Showing the first eight; more decompositions exist.
