Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705644, here are decompositions:

5 + 8705639 = 8705644
71 + 8705573 = 8705644
83 + 8705561 = 8705644
113 + 8705531 = 8705644
137 + 8705507 = 8705644
191 + 8705453 = 8705644
293 + 8705351 = 8705644
347 + 8705297 = 8705644

Showing the first eight; more decompositions exist.
