Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532844, here are decompositions:

11 + 31532833 = 31532844
67 + 31532777 = 31532844
107 + 31532737 = 31532844
151 + 31532693 = 31532844
157 + 31532687 = 31532844
191 + 31532653 = 31532844
251 + 31532593 = 31532844
257 + 31532587 = 31532844

Showing the first eight; more decompositions exist.
