Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525348, here are decompositions:

5 + 31525343 = 31525348
17 + 31525331 = 31525348
59 + 31525289 = 31525348
137 + 31525211 = 31525348
227 + 31525121 = 31525348
311 + 31525037 = 31525348
317 + 31525031 = 31525348
359 + 31524989 = 31525348

Showing the first eight; more decompositions exist.
