Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588462, here are decompositions:

23 + 31588439 = 31588462
131 + 31588331 = 31588462
149 + 31588313 = 31588462
263 + 31588199 = 31588462
359 + 31588103 = 31588462
401 + 31588061 = 31588462
443 + 31588019 = 31588462
569 + 31587893 = 31588462

Showing the first eight; more decompositions exist.
