Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655190, here are decompositions:

17 + 8655173 = 8655190
23 + 8655167 = 8655190
41 + 8655149 = 8655190
149 + 8655041 = 8655190
179 + 8655011 = 8655190
293 + 8654897 = 8655190
317 + 8654873 = 8655190
353 + 8654837 = 8655190

Showing the first eight; more decompositions exist.
