Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532792, here are decompositions:

43 + 31532749 = 31532792
139 + 31532653 = 31532792
199 + 31532593 = 31532792
211 + 31532581 = 31532792
241 + 31532551 = 31532792
271 + 31532521 = 31532792
439 + 31532353 = 31532792
463 + 31532329 = 31532792

Showing the first eight; more decompositions exist.
