Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8070, here are decompositions:

11 + 8059 = 8070
17 + 8053 = 8070
31 + 8039 = 8070
53 + 8017 = 8070
59 + 8011 = 8070
61 + 8009 = 8070
107 + 7963 = 8070
137 + 7933 = 8070

Showing the first eight; more decompositions exist.
