Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624350, here are decompositions:

7 + 31624343 = 31624350
11 + 31624339 = 31624350
13 + 31624337 = 31624350
19 + 31624331 = 31624350
29 + 31624321 = 31624350
67 + 31624283 = 31624350
73 + 31624277 = 31624350
223 + 31624127 = 31624350

Showing the first eight; more decompositions exist.
