Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532894, here are decompositions:

13 + 31532881 = 31532894
31 + 31532863 = 31532894
61 + 31532833 = 31532894
157 + 31532737 = 31532894
241 + 31532653 = 31532894
307 + 31532587 = 31532894
313 + 31532581 = 31532894
373 + 31532521 = 31532894

Showing the first eight; more decompositions exist.
