Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664378, here are decompositions:

11 + 8664367 = 8664378
61 + 8664317 = 8664378
67 + 8664311 = 8664378
197 + 8664181 = 8664378
269 + 8664109 = 8664378
271 + 8664107 = 8664378
409 + 8663969 = 8664378
419 + 8663959 = 8664378

Showing the first eight; more decompositions exist.
