Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722376, here are decompositions:

37 + 8722339 = 8722376
43 + 8722333 = 8722376
73 + 8722303 = 8722376
79 + 8722297 = 8722376
139 + 8722237 = 8722376
277 + 8722099 = 8722376
283 + 8722093 = 8722376
349 + 8722027 = 8722376

Showing the first eight; more decompositions exist.
