Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743860, here are decompositions:

7 + 8743853 = 8743860
17 + 8743843 = 8743860
23 + 8743837 = 8743860
43 + 8743817 = 8743860
53 + 8743807 = 8743860
89 + 8743771 = 8743860
107 + 8743753 = 8743860
113 + 8743747 = 8743860

Showing the first eight; more decompositions exist.
