Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745858, here are decompositions:

29 + 8745829 = 8745858
31 + 8745827 = 8745858
41 + 8745817 = 8745858
59 + 8745799 = 8745858
109 + 8745749 = 8745858
179 + 8745679 = 8745858
181 + 8745677 = 8745858
307 + 8745551 = 8745858

Showing the first eight; more decompositions exist.
