Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8072, here are decompositions:

3 + 8069 = 8072
13 + 8059 = 8072
19 + 8053 = 8072
61 + 8011 = 8072
79 + 7993 = 8072
109 + 7963 = 8072
139 + 7933 = 8072
193 + 7879 = 8072

Showing the first eight; more decompositions exist.
