Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532912, here are decompositions:

13 + 31532899 = 31532912
31 + 31532881 = 31532912
79 + 31532833 = 31532912
163 + 31532749 = 31532912
331 + 31532581 = 31532912
373 + 31532539 = 31532912
571 + 31532341 = 31532912
643 + 31532269 = 31532912

Showing the first eight; more decompositions exist.
