Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619442, here are decompositions:

3 + 8619439 = 8619442
5 + 8619437 = 8619442
11 + 8619431 = 8619442
89 + 8619353 = 8619442
173 + 8619269 = 8619442
179 + 8619263 = 8619442
311 + 8619131 = 8619442
383 + 8619059 = 8619442

Showing the first eight; more decompositions exist.
