Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722340, here are decompositions:

7 + 8722333 = 8722340
37 + 8722303 = 8722340
43 + 8722297 = 8722340
103 + 8722237 = 8722340
223 + 8722117 = 8722340
241 + 8722099 = 8722340
307 + 8722033 = 8722340
313 + 8722027 = 8722340

Showing the first eight; more decompositions exist.
