Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621832, here are decompositions:

5 + 8621827 = 8621832
13 + 8621819 = 8621832
53 + 8621779 = 8621832
59 + 8621773 = 8621832
83 + 8621749 = 8621832
139 + 8621693 = 8621832
151 + 8621681 = 8621832
179 + 8621653 = 8621832

Showing the first eight; more decompositions exist.
