Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622242, here are decompositions:

19 + 8622223 = 8622242
241 + 8622001 = 8622242
271 + 8621971 = 8622242
283 + 8621959 = 8622242
331 + 8621911 = 8622242
373 + 8621869 = 8622242
379 + 8621863 = 8622242
463 + 8621779 = 8622242

Showing the first eight; more decompositions exist.
