Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619450, here are decompositions:

11 + 8619439 = 8619450
13 + 8619437 = 8619450
17 + 8619433 = 8619450
19 + 8619431 = 8619450
23 + 8619427 = 8619450
29 + 8619421 = 8619450
53 + 8619397 = 8619450
97 + 8619353 = 8619450

Showing the first eight; more decompositions exist.
