Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6140, here are decompositions:

7 + 6133 = 6140
19 + 6121 = 6140
61 + 6079 = 6140
67 + 6073 = 6140
73 + 6067 = 6140
97 + 6043 = 6140
103 + 6037 = 6140
271 + 5869 = 6140

Showing the first eight; more decompositions exist.
