Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10940, here are decompositions:

3 + 10937 = 10940
31 + 10909 = 10940
37 + 10903 = 10940
73 + 10867 = 10940
79 + 10861 = 10940
103 + 10837 = 10940
109 + 10831 = 10940
151 + 10789 = 10940

Showing the first eight; more decompositions exist.
