Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525394, here are decompositions:

127 + 31525267 = 31525394
151 + 31525243 = 31525394
181 + 31525213 = 31525394
193 + 31525201 = 31525394
211 + 31525183 = 31525394
367 + 31525027 = 31525394
457 + 31524937 = 31525394
601 + 31524793 = 31525394

Showing the first eight; more decompositions exist.
