Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743900, here are decompositions:

17 + 8743883 = 8743900
47 + 8743853 = 8743900
83 + 8743817 = 8743900
131 + 8743769 = 8743900
167 + 8743733 = 8743900
227 + 8743673 = 8743900
311 + 8743589 = 8743900
317 + 8743583 = 8743900

Showing the first eight; more decompositions exist.
