Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624708, here are decompositions:

47 + 31624661 = 31624708
149 + 31624559 = 31624708
197 + 31624511 = 31624708
251 + 31624457 = 31624708
359 + 31624349 = 31624708
431 + 31624277 = 31624708
491 + 31624217 = 31624708
719 + 31623989 = 31624708

Showing the first eight; more decompositions exist.
