Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684828, here are decompositions:

7 + 8684821 = 8684828
67 + 8684761 = 8684828
199 + 8684629 = 8684828
241 + 8684587 = 8684828
307 + 8684521 = 8684828
349 + 8684479 = 8684828
367 + 8684461 = 8684828
409 + 8684419 = 8684828

Showing the first eight; more decompositions exist.
