Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619444, here are decompositions:

5 + 8619439 = 8619444
7 + 8619437 = 8619444
11 + 8619433 = 8619444
13 + 8619431 = 8619444
17 + 8619427 = 8619444
23 + 8619421 = 8619444
47 + 8619397 = 8619444
101 + 8619343 = 8619444

Showing the first eight; more decompositions exist.
