Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582948, here are decompositions:

11 + 31582937 = 31582948
17 + 31582931 = 31582948
41 + 31582907 = 31582948
101 + 31582847 = 31582948
167 + 31582781 = 31582948
191 + 31582757 = 31582948
269 + 31582679 = 31582948
281 + 31582667 = 31582948

Showing the first eight; more decompositions exist.
