Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588104, here are decompositions:

17 + 31588087 = 31588104
43 + 31588061 = 31588104
101 + 31588003 = 31588104
181 + 31587923 = 31588104
193 + 31587911 = 31588104
211 + 31587893 = 31588104
227 + 31587877 = 31588104
311 + 31587793 = 31588104

Showing the first eight; more decompositions exist.
