Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690086, here are decompositions:

17 + 8690069 = 8690086
23 + 8690063 = 8690086
89 + 8689997 = 8690086
107 + 8689979 = 8690086
137 + 8689949 = 8690086
233 + 8689853 = 8690086
263 + 8689823 = 8690086
269 + 8689817 = 8690086

Showing the first eight; more decompositions exist.
