Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624600, here are decompositions:

3 + 31624597 = 31624600
41 + 31624559 = 31624600
53 + 31624547 = 31624600
89 + 31624511 = 31624600
233 + 31624367 = 31624600
251 + 31624349 = 31624600
257 + 31624343 = 31624600
263 + 31624337 = 31624600

Showing the first eight; more decompositions exist.
