Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624582, here are decompositions:

23 + 31624559 = 31624582
71 + 31624511 = 31624582
233 + 31624349 = 31624582
239 + 31624343 = 31624582
251 + 31624331 = 31624582
569 + 31624013 = 31624582
593 + 31623989 = 31624582
599 + 31623983 = 31624582

Showing the first eight; more decompositions exist.
