Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78140, here are decompositions:

3 + 78137 = 78140
19 + 78121 = 78140
61 + 78079 = 78140
109 + 78031 = 78140
157 + 77983 = 78140
163 + 77977 = 78140
211 + 77929 = 78140
241 + 77899 = 78140

Showing the first eight; more decompositions exist.
