Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525336, here are decompositions:

5 + 31525331 = 31525336
47 + 31525289 = 31525336
53 + 31525283 = 31525336
107 + 31525229 = 31525336
173 + 31525163 = 31525336
233 + 31525103 = 31525336
347 + 31524989 = 31525336
443 + 31524893 = 31525336

Showing the first eight; more decompositions exist.
