Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722828, here are decompositions:

29 + 8722799 = 8722828
71 + 8722757 = 8722828
89 + 8722739 = 8722828
167 + 8722661 = 8722828
197 + 8722631 = 8722828
311 + 8722517 = 8722828
419 + 8722409 = 8722828
461 + 8722367 = 8722828

Showing the first eight; more decompositions exist.
