Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622320, here are decompositions:

13 + 8622307 = 8622320
19 + 8622301 = 8622320
79 + 8622241 = 8622320
97 + 8622223 = 8622320
193 + 8622127 = 8622320
313 + 8622007 = 8622320
331 + 8621989 = 8622320
337 + 8621983 = 8622320

Showing the first eight; more decompositions exist.
