Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722346, here are decompositions:

7 + 8722339 = 8722346
13 + 8722333 = 8722346
43 + 8722303 = 8722346
109 + 8722237 = 8722346
223 + 8722123 = 8722346
229 + 8722117 = 8722346
313 + 8722033 = 8722346
337 + 8722009 = 8722346

Showing the first eight; more decompositions exist.
