Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482588, here are decompositions:

19 + 31482569 = 31482588
29 + 31482559 = 31482588
37 + 31482551 = 31482588
79 + 31482509 = 31482588
89 + 31482499 = 31482588
149 + 31482439 = 31482588
199 + 31482389 = 31482588
239 + 31482349 = 31482588

Showing the first eight; more decompositions exist.
