Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612740, here are decompositions:

11 + 8612729 = 8612740
29 + 8612711 = 8612740
53 + 8612687 = 8612740
83 + 8612657 = 8612740
107 + 8612633 = 8612740
113 + 8612627 = 8612740
317 + 8612423 = 8612740
641 + 8612099 = 8612740

Showing the first eight; more decompositions exist.
