Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640090, here are decompositions:

31 + 8640059 = 8640090
73 + 8640017 = 8640090
89 + 8640001 = 8640090
103 + 8639987 = 8640090
113 + 8639977 = 8640090
139 + 8639951 = 8640090
167 + 8639923 = 8640090
181 + 8639909 = 8640090

Showing the first eight; more decompositions exist.
