Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743284, here are decompositions:

5 + 8743279 = 8743284
7 + 8743277 = 8743284
23 + 8743261 = 8743284
71 + 8743213 = 8743284
163 + 8743121 = 8743284
181 + 8743103 = 8743284
197 + 8743087 = 8743284
241 + 8743043 = 8743284

Showing the first eight; more decompositions exist.
