Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624370, here are decompositions:

3 + 31624367 = 31624370
7 + 31624363 = 31624370
13 + 31624357 = 31624370
31 + 31624339 = 31624370
223 + 31624147 = 31624370
229 + 31624141 = 31624370
241 + 31624129 = 31624370
367 + 31624003 = 31624370

Showing the first eight; more decompositions exist.
