Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624458, here are decompositions:

29 + 31624429 = 31624458
71 + 31624387 = 31624458
101 + 31624357 = 31624458
109 + 31624349 = 31624458
127 + 31624331 = 31624458
137 + 31624321 = 31624458
181 + 31624277 = 31624458
241 + 31624217 = 31624458

Showing the first eight; more decompositions exist.
