Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597872, here are decompositions:

29 + 8597843 = 8597872
89 + 8597783 = 8597872
113 + 8597759 = 8597872
149 + 8597723 = 8597872
233 + 8597639 = 8597872
251 + 8597621 = 8597872
281 + 8597591 = 8597872
401 + 8597471 = 8597872

Showing the first eight; more decompositions exist.
