Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743864, here are decompositions:

11 + 8743853 = 8743864
47 + 8743817 = 8743864
131 + 8743733 = 8743864
191 + 8743673 = 8743864
281 + 8743583 = 8743864
293 + 8743571 = 8743864
317 + 8743547 = 8743864
443 + 8743421 = 8743864

Showing the first eight; more decompositions exist.
