Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664438, here are decompositions:

5 + 8664433 = 8664438
7 + 8664431 = 8664438
11 + 8664427 = 8664438
17 + 8664421 = 8664438
19 + 8664419 = 8664438
61 + 8664377 = 8664438
71 + 8664367 = 8664438
109 + 8664329 = 8664438

Showing the first eight; more decompositions exist.
