Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724396, here are decompositions:

19 + 8724377 = 8724396
67 + 8724329 = 8724396
73 + 8724323 = 8724396
103 + 8724293 = 8724396
113 + 8724283 = 8724396
127 + 8724269 = 8724396
137 + 8724259 = 8724396
173 + 8724223 = 8724396

Showing the first eight; more decompositions exist.
