Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532832, here are decompositions:

83 + 31532749 = 31532832
139 + 31532693 = 31532832
173 + 31532659 = 31532832
179 + 31532653 = 31532832
193 + 31532639 = 31532832
239 + 31532593 = 31532832
251 + 31532581 = 31532832
281 + 31532551 = 31532832

Showing the first eight; more decompositions exist.
