Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532924, here are decompositions:

43 + 31532881 = 31532924
61 + 31532863 = 31532924
271 + 31532653 = 31532924
331 + 31532593 = 31532924
337 + 31532587 = 31532924
373 + 31532551 = 31532924
487 + 31532437 = 31532924
523 + 31532401 = 31532924

Showing the first eight; more decompositions exist.
