Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582848, here are decompositions:

29 + 31582819 = 31582848
67 + 31582781 = 31582848
71 + 31582777 = 31582848
109 + 31582739 = 31582848
181 + 31582667 = 31582848
239 + 31582609 = 31582848
317 + 31582531 = 31582848
359 + 31582489 = 31582848

Showing the first eight; more decompositions exist.
