Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624596, here are decompositions:

5 + 31624591 = 31624596
37 + 31624559 = 31624596
89 + 31624507 = 31624596
139 + 31624457 = 31624596
167 + 31624429 = 31624596
173 + 31624423 = 31624596
229 + 31624367 = 31624596
233 + 31624363 = 31624596

Showing the first eight; more decompositions exist.
