Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624568, here are decompositions:

61 + 31624507 = 31624568
139 + 31624429 = 31624568
181 + 31624387 = 31624568
211 + 31624357 = 31624568
229 + 31624339 = 31624568
421 + 31624147 = 31624568
439 + 31624129 = 31624568
499 + 31624069 = 31624568

Showing the first eight; more decompositions exist.
