Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484588, here are decompositions:

19 + 31484569 = 31484588
127 + 31484461 = 31484588
139 + 31484449 = 31484588
211 + 31484377 = 31484588
229 + 31484359 = 31484588
271 + 31484317 = 31484588
307 + 31484281 = 31484588
349 + 31484239 = 31484588

Showing the first eight; more decompositions exist.
