Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525370, here are decompositions:

3 + 31525367 = 31525370
103 + 31525267 = 31525370
109 + 31525261 = 31525370
127 + 31525243 = 31525370
157 + 31525213 = 31525370
193 + 31525177 = 31525370
379 + 31524991 = 31525370
433 + 31524937 = 31525370

Showing the first eight; more decompositions exist.
