Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658090, here are decompositions:

31 + 8658059 = 8658090
47 + 8658043 = 8658090
73 + 8658017 = 8658090
107 + 8657983 = 8658090
157 + 8657933 = 8658090
163 + 8657927 = 8658090
167 + 8657923 = 8658090
239 + 8657851 = 8658090

Showing the first eight; more decompositions exist.
