Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726646, here are decompositions:

13 + 8726633 = 8726646
59 + 8726587 = 8726646
73 + 8726573 = 8726646
113 + 8726533 = 8726646
139 + 8726507 = 8726646
167 + 8726479 = 8726646
179 + 8726467 = 8726646
197 + 8726449 = 8726646

Showing the first eight; more decompositions exist.
