Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644264, here are decompositions:

3 + 8644261 = 8644264
11 + 8644253 = 8644264
107 + 8644157 = 8644264
173 + 8644091 = 8644264
311 + 8643953 = 8644264
443 + 8643821 = 8644264
467 + 8643797 = 8644264
557 + 8643707 = 8644264

Showing the first eight; more decompositions exist.
