Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624558, here are decompositions:

11 + 31624547 = 31624558
47 + 31624511 = 31624558
101 + 31624457 = 31624558
191 + 31624367 = 31624558
227 + 31624331 = 31624558
281 + 31624277 = 31624558
431 + 31624127 = 31624558
557 + 31624001 = 31624558

Showing the first eight; more decompositions exist.
