Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655460, here are decompositions:

3 + 8655457 = 8655460
59 + 8655401 = 8655460
89 + 8655371 = 8655460
173 + 8655287 = 8655460
197 + 8655263 = 8655460
263 + 8655197 = 8655460
293 + 8655167 = 8655460
311 + 8655149 = 8655460

Showing the first eight; more decompositions exist.
