Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655130, here are decompositions:

59 + 8655071 = 8655130
83 + 8655047 = 8655130
89 + 8655041 = 8655130
101 + 8655029 = 8655130
149 + 8654981 = 8655130
233 + 8654897 = 8655130
257 + 8654873 = 8655130
293 + 8654837 = 8655130

Showing the first eight; more decompositions exist.
