Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4970, here are decompositions:

3 + 4967 = 4970
13 + 4957 = 4970
19 + 4951 = 4970
37 + 4933 = 4970
61 + 4909 = 4970
67 + 4903 = 4970
109 + 4861 = 4970
139 + 4831 = 4970

Showing the first eight; more decompositions exist.
