Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622224, here are decompositions:

97 + 8622127 = 8622224
223 + 8622001 = 8622224
241 + 8621983 = 8622224
277 + 8621947 = 8622224
313 + 8621911 = 8622224
367 + 8621857 = 8622224
397 + 8621827 = 8622224
547 + 8621677 = 8622224

Showing the first eight; more decompositions exist.
