Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4988, here are decompositions:

19 + 4969 = 4988
31 + 4957 = 4988
37 + 4951 = 4988
79 + 4909 = 4988
127 + 4861 = 4988
157 + 4831 = 4988
199 + 4789 = 4988
229 + 4759 = 4988

Showing the first eight; more decompositions exist.
