Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743320, here are decompositions:

11 + 8743309 = 8743320
41 + 8743279 = 8743320
43 + 8743277 = 8743320
59 + 8743261 = 8743320
107 + 8743213 = 8743320
151 + 8743169 = 8743320
181 + 8743139 = 8743320
199 + 8743121 = 8743320

Showing the first eight; more decompositions exist.
