Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655550, here are decompositions:

23 + 8655527 = 8655550
53 + 8655497 = 8655550
149 + 8655401 = 8655550
179 + 8655371 = 8655550
263 + 8655287 = 8655550
353 + 8655197 = 8655550
383 + 8655167 = 8655550
401 + 8655149 = 8655550

Showing the first eight; more decompositions exist.
