Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644622, here are decompositions:

13 + 8644609 = 8644622
379 + 8644243 = 8644622
409 + 8644213 = 8644622
499 + 8644123 = 8644622
541 + 8644081 = 8644622
631 + 8643991 = 8644622
733 + 8643889 = 8644622
991 + 8643631 = 8644622

Showing the first eight; more decompositions exist.
