Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532874, here are decompositions:

7 + 31532867 = 31532874
11 + 31532863 = 31532874
41 + 31532833 = 31532874
97 + 31532777 = 31532874
137 + 31532737 = 31532874
181 + 31532693 = 31532874
277 + 31532597 = 31532874
281 + 31532593 = 31532874

Showing the first eight; more decompositions exist.
