Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624338, here are decompositions:

7 + 31624331 = 31624338
17 + 31624321 = 31624338
61 + 31624277 = 31624338
191 + 31624147 = 31624338
197 + 31624141 = 31624338
211 + 31624127 = 31624338
269 + 31624069 = 31624338
337 + 31624001 = 31624338

Showing the first eight; more decompositions exist.
