Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618846, here are decompositions:

13 + 8618833 = 8618846
37 + 8618809 = 8618846
97 + 8618749 = 8618846
109 + 8618737 = 8618846
157 + 8618689 = 8618846
163 + 8618683 = 8618846
367 + 8618479 = 8618846
433 + 8618413 = 8618846

Showing the first eight; more decompositions exist.
