Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722382, here are decompositions:

43 + 8722339 = 8722382
79 + 8722303 = 8722382
211 + 8722171 = 8722382
283 + 8722099 = 8722382
349 + 8722033 = 8722382
373 + 8722009 = 8722382
499 + 8721883 = 8722382
619 + 8721763 = 8722382

Showing the first eight; more decompositions exist.
