Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625306, here are decompositions:

3 + 31625303 = 31625306
43 + 31625263 = 31625306
127 + 31625179 = 31625306
157 + 31625149 = 31625306
367 + 31624939 = 31625306
379 + 31624927 = 31625306
457 + 31624849 = 31625306
499 + 31624807 = 31625306

Showing the first eight; more decompositions exist.
