Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525162, here are decompositions:

41 + 31525121 = 31525162
59 + 31525103 = 31525162
131 + 31525031 = 31525162
173 + 31524989 = 31525162
269 + 31524893 = 31525162
353 + 31524809 = 31525162
521 + 31524641 = 31525162
593 + 31524569 = 31525162

Showing the first eight; more decompositions exist.
