Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612588, here are decompositions:

5 + 31612583 = 31612588
41 + 31612547 = 31612588
101 + 31612487 = 31612588
107 + 31612481 = 31612588
197 + 31612391 = 31612588
281 + 31612307 = 31612588
311 + 31612277 = 31612588
347 + 31612241 = 31612588

Showing the first eight; more decompositions exist.
