Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8090, here are decompositions:

3 + 8087 = 8090
31 + 8059 = 8090
37 + 8053 = 8090
73 + 8017 = 8090
79 + 8011 = 8090
97 + 7993 = 8090
127 + 7963 = 8090
139 + 7951 = 8090

Showing the first eight; more decompositions exist.
