Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732920, here are decompositions:

41 + 8732879 = 8732920
59 + 8732861 = 8732920
89 + 8732831 = 8732920
101 + 8732819 = 8732920
113 + 8732807 = 8732920
233 + 8732687 = 8732920
281 + 8732639 = 8732920
293 + 8732627 = 8732920

Showing the first eight; more decompositions exist.
