Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525066, here are decompositions:

29 + 31525037 = 31525066
59 + 31525007 = 31525066
173 + 31524893 = 31525066
227 + 31524839 = 31525066
257 + 31524809 = 31525066
269 + 31524797 = 31525066
389 + 31524677 = 31525066
479 + 31524587 = 31525066

Showing the first eight; more decompositions exist.
