Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655394, here are decompositions:

23 + 8655371 = 8655394
107 + 8655287 = 8655394
131 + 8655263 = 8655394
197 + 8655197 = 8655394
227 + 8655167 = 8655394
347 + 8655047 = 8655394
353 + 8655041 = 8655394
383 + 8655011 = 8655394

Showing the first eight; more decompositions exist.
