Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588204, here are decompositions:

3 + 31588201 = 31588204
5 + 31588199 = 31588204
47 + 31588157 = 31588204
101 + 31588103 = 31588204
281 + 31587923 = 31588204
293 + 31587911 = 31588204
311 + 31587893 = 31588204
467 + 31587737 = 31588204

Showing the first eight; more decompositions exist.
