Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644136, here are decompositions:

13 + 8644123 = 8644136
79 + 8644057 = 8644136
139 + 8643997 = 8644136
349 + 8643787 = 8644136
379 + 8643757 = 8644136
439 + 8643697 = 8644136
463 + 8643673 = 8644136
547 + 8643589 = 8644136

Showing the first eight; more decompositions exist.
