Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588282, here are decompositions:

29 + 31588253 = 31588282
83 + 31588199 = 31588282
179 + 31588103 = 31588282
263 + 31588019 = 31588282
359 + 31587923 = 31588282
389 + 31587893 = 31588282
503 + 31587779 = 31588282
659 + 31587623 = 31588282

Showing the first eight; more decompositions exist.
