Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690222, here are decompositions:

19 + 8690203 = 8690222
31 + 8690191 = 8690222
103 + 8690119 = 8690222
181 + 8690041 = 8690222
241 + 8689981 = 8690222
379 + 8689843 = 8690222
613 + 8689609 = 8690222
631 + 8689591 = 8690222

Showing the first eight; more decompositions exist.
