Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532876, here are decompositions:

3 + 31532873 = 31532876
13 + 31532863 = 31532876
43 + 31532833 = 31532876
127 + 31532749 = 31532876
139 + 31532737 = 31532876
223 + 31532653 = 31532876
283 + 31532593 = 31532876
337 + 31532539 = 31532876

Showing the first eight; more decompositions exist.
