Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532918, here are decompositions:

19 + 31532899 = 31532918
37 + 31532881 = 31532918
181 + 31532737 = 31532918
331 + 31532587 = 31532918
337 + 31532581 = 31532918
367 + 31532551 = 31532918
379 + 31532539 = 31532918
397 + 31532521 = 31532918

Showing the first eight; more decompositions exist.
