Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644406, here are decompositions:

79 + 8644327 = 8644406
163 + 8644243 = 8644406
193 + 8644213 = 8644406
283 + 8644123 = 8644406
349 + 8644057 = 8644406
409 + 8643997 = 8644406
487 + 8643919 = 8644406
619 + 8643787 = 8644406

Showing the first eight; more decompositions exist.
