Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3140, here are decompositions:

3 + 3137 = 3140
19 + 3121 = 3140
31 + 3109 = 3140
61 + 3079 = 3140
73 + 3067 = 3140
79 + 3061 = 3140
103 + 3037 = 3140
139 + 3001 = 3140

Showing the first eight; more decompositions exist.
