Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525636, here are decompositions:

29 + 31525607 = 31525636
47 + 31525589 = 31525636
83 + 31525553 = 31525636
137 + 31525499 = 31525636
239 + 31525397 = 31525636
257 + 31525379 = 31525636
269 + 31525367 = 31525636
293 + 31525343 = 31525636

Showing the first eight; more decompositions exist.
