Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644774, here are decompositions:

3 + 8644771 = 8644774
23 + 8644751 = 8644774
71 + 8644703 = 8644774
113 + 8644661 = 8644774
167 + 8644607 = 8644774
263 + 8644511 = 8644774
317 + 8644457 = 8644774
443 + 8644331 = 8644774

Showing the first eight; more decompositions exist.
