Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532672, here are decompositions:

13 + 31532659 = 31532672
19 + 31532653 = 31532672
79 + 31532593 = 31532672
151 + 31532521 = 31532672
271 + 31532401 = 31532672
331 + 31532341 = 31532672
349 + 31532323 = 31532672
463 + 31532209 = 31532672

Showing the first eight; more decompositions exist.
