Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743398, here are decompositions:

5 + 8743393 = 8743398
19 + 8743379 = 8743398
31 + 8743367 = 8743398
67 + 8743331 = 8743398
71 + 8743327 = 8743398
89 + 8743309 = 8743398
137 + 8743261 = 8743398
229 + 8743169 = 8743398

Showing the first eight; more decompositions exist.
