Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743984, here are decompositions:

3 + 8743981 = 8743984
47 + 8743937 = 8743984
71 + 8743913 = 8743984
83 + 8743901 = 8743984
101 + 8743883 = 8743984
131 + 8743853 = 8743984
167 + 8743817 = 8743984
251 + 8743733 = 8743984

Showing the first eight; more decompositions exist.
