Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532784, here are decompositions:

7 + 31532777 = 31532784
47 + 31532737 = 31532784
97 + 31532687 = 31532784
131 + 31532653 = 31532784
191 + 31532593 = 31532784
197 + 31532587 = 31532784
211 + 31532573 = 31532784
233 + 31532551 = 31532784

Showing the first eight; more decompositions exist.
