Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4940, here are decompositions:

3 + 4937 = 4940
7 + 4933 = 4940
31 + 4909 = 4940
37 + 4903 = 4940
79 + 4861 = 4940
109 + 4831 = 4940
127 + 4813 = 4940
139 + 4801 = 4940

Showing the first eight; more decompositions exist.
