Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736858, here are decompositions:

5 + 8736853 = 8736858
41 + 8736817 = 8736858
59 + 8736799 = 8736858
71 + 8736787 = 8736858
131 + 8736727 = 8736858
139 + 8736719 = 8736858
157 + 8736701 = 8736858
191 + 8736667 = 8736858

Showing the first eight; more decompositions exist.
