Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644802, here are decompositions:

3 + 8644799 = 8644802
31 + 8644771 = 8644802
73 + 8644729 = 8644802
79 + 8644723 = 8644802
151 + 8644651 = 8644802
193 + 8644609 = 8644802
349 + 8644453 = 8644802
541 + 8644261 = 8644802

Showing the first eight; more decompositions exist.
