Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624230, here are decompositions:

13 + 31624217 = 31624230
83 + 31624147 = 31624230
89 + 31624141 = 31624230
101 + 31624129 = 31624230
103 + 31624127 = 31624230
227 + 31624003 = 31624230
229 + 31624001 = 31624230
241 + 31623989 = 31624230

Showing the first eight; more decompositions exist.
