Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644808, here are decompositions:

37 + 8644771 = 8644808
79 + 8644729 = 8644808
157 + 8644651 = 8644808
199 + 8644609 = 8644808
307 + 8644501 = 8644808
331 + 8644477 = 8644808
547 + 8644261 = 8644808
577 + 8644231 = 8644808

Showing the first eight; more decompositions exist.
