Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619340, here are decompositions:

71 + 8619269 = 8619340
173 + 8619167 = 8619340
239 + 8619101 = 8619340
263 + 8619077 = 8619340
269 + 8619071 = 8619340
281 + 8619059 = 8619340
461 + 8618879 = 8619340
479 + 8618861 = 8619340

Showing the first eight; more decompositions exist.
