Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655446, here are decompositions:

13 + 8655433 = 8655446
43 + 8655403 = 8655446
97 + 8655349 = 8655446
103 + 8655343 = 8655446
139 + 8655307 = 8655446
229 + 8655217 = 8655446
409 + 8655037 = 8655446
439 + 8655007 = 8655446

Showing the first eight; more decompositions exist.
