Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622380, here are decompositions:

7 + 8622373 = 8622380
37 + 8622343 = 8622380
43 + 8622337 = 8622380
73 + 8622307 = 8622380
79 + 8622301 = 8622380
139 + 8622241 = 8622380
157 + 8622223 = 8622380
373 + 8622007 = 8622380

Showing the first eight; more decompositions exist.
