Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644804, here are decompositions:

5 + 8644799 = 8644804
23 + 8644781 = 8644804
53 + 8644751 = 8644804
101 + 8644703 = 8644804
197 + 8644607 = 8644804
251 + 8644553 = 8644804
293 + 8644511 = 8644804
347 + 8644457 = 8644804

Showing the first eight; more decompositions exist.
