Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532948, here are decompositions:

67 + 31532881 = 31532948
199 + 31532749 = 31532948
211 + 31532737 = 31532948
367 + 31532581 = 31532948
397 + 31532551 = 31532948
409 + 31532539 = 31532948
547 + 31532401 = 31532948
607 + 31532341 = 31532948

Showing the first eight; more decompositions exist.
