Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525084, here are decompositions:

47 + 31525037 = 31525084
53 + 31525031 = 31525084
191 + 31524893 = 31525084
293 + 31524791 = 31525084
317 + 31524767 = 31525084
443 + 31524641 = 31525084
827 + 31524257 = 31525084
887 + 31524197 = 31525084

Showing the first eight; more decompositions exist.
