Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590882, here are decompositions:

5 + 31590877 = 31590882
41 + 31590841 = 31590882
79 + 31590803 = 31590882
149 + 31590733 = 31590882
151 + 31590731 = 31590882
199 + 31590683 = 31590882
223 + 31590659 = 31590882
233 + 31590649 = 31590882

Showing the first eight; more decompositions exist.
