Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709844, here are decompositions:

5 + 8709839 = 8709844
23 + 8709821 = 8709844
107 + 8709737 = 8709844
113 + 8709731 = 8709844
131 + 8709713 = 8709844
167 + 8709677 = 8709844
191 + 8709653 = 8709844
197 + 8709647 = 8709844

Showing the first eight; more decompositions exist.
