Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102140, here are decompositions:

19 + 102121 = 102140
37 + 102103 = 102140
61 + 102079 = 102140
79 + 102061 = 102140
97 + 102043 = 102140
109 + 102031 = 102140
127 + 102013 = 102140
139 + 102001 = 102140

Showing the first eight; more decompositions exist.
