Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8150, here are decompositions:

3 + 8147 = 8150
61 + 8089 = 8150
97 + 8053 = 8150
139 + 8011 = 8150
157 + 7993 = 8150
199 + 7951 = 8150
223 + 7927 = 8150
271 + 7879 = 8150

Showing the first eight; more decompositions exist.
