Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532582, here are decompositions:

31 + 31532551 = 31532582
43 + 31532539 = 31532582
61 + 31532521 = 31532582
181 + 31532401 = 31532582
229 + 31532353 = 31532582
241 + 31532341 = 31532582
313 + 31532269 = 31532582
373 + 31532209 = 31532582

Showing the first eight; more decompositions exist.
