Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690216, here are decompositions:

13 + 8690203 = 8690216
43 + 8690173 = 8690216
97 + 8690119 = 8690216
127 + 8690089 = 8690216
229 + 8689987 = 8690216
373 + 8689843 = 8690216
439 + 8689777 = 8690216
463 + 8689753 = 8690216

Showing the first eight; more decompositions exist.
