Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619372, here are decompositions:

19 + 8619353 = 8619372
29 + 8619343 = 8619372
103 + 8619269 = 8619372
109 + 8619263 = 8619372
131 + 8619241 = 8619372
149 + 8619223 = 8619372
173 + 8619199 = 8619372
241 + 8619131 = 8619372

Showing the first eight; more decompositions exist.
