Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624588, here are decompositions:

29 + 31624559 = 31624588
41 + 31624547 = 31624588
131 + 31624457 = 31624588
239 + 31624349 = 31624588
251 + 31624337 = 31624588
257 + 31624331 = 31624588
311 + 31624277 = 31624588
461 + 31624127 = 31624588

Showing the first eight; more decompositions exist.
