Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624602, here are decompositions:

5 + 31624597 = 31624602
11 + 31624591 = 31624602
43 + 31624559 = 31624602
173 + 31624429 = 31624602
179 + 31624423 = 31624602
239 + 31624363 = 31624602
263 + 31624339 = 31624602
271 + 31624331 = 31624602

Showing the first eight; more decompositions exist.
