Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622378, here are decompositions:

5 + 8622373 = 8622378
19 + 8622359 = 8622378
41 + 8622337 = 8622378
47 + 8622331 = 8622378
71 + 8622307 = 8622378
137 + 8622241 = 8622378
241 + 8622137 = 8622378
251 + 8622127 = 8622378

Showing the first eight; more decompositions exist.
