Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618700, here are decompositions:

11 + 8618689 = 8618700
17 + 8618683 = 8618700
19 + 8618681 = 8618700
61 + 8618639 = 8618700
107 + 8618593 = 8618700
109 + 8618591 = 8618700
199 + 8618501 = 8618700
257 + 8618443 = 8618700

Showing the first eight; more decompositions exist.
