Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655426, here are decompositions:

5 + 8655421 = 8655426
23 + 8655403 = 8655426
83 + 8655343 = 8655426
113 + 8655313 = 8655426
139 + 8655287 = 8655426
163 + 8655263 = 8655426
167 + 8655259 = 8655426
229 + 8655197 = 8655426

Showing the first eight; more decompositions exist.
