Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619370, here are decompositions:

17 + 8619353 = 8619370
101 + 8619269 = 8619370
107 + 8619263 = 8619370
173 + 8619197 = 8619370
239 + 8619131 = 8619370
269 + 8619101 = 8619370
293 + 8619077 = 8619370
311 + 8619059 = 8619370

Showing the first eight; more decompositions exist.
