Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600090, here are decompositions:

19 + 8600071 = 8600090
43 + 8600047 = 8600090
61 + 8600029 = 8600090
67 + 8600023 = 8600090
97 + 8599993 = 8600090
193 + 8599897 = 8600090
199 + 8599891 = 8600090
223 + 8599867 = 8600090

Showing the first eight; more decompositions exist.
