Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4030, here are decompositions:

3 + 4027 = 4030
11 + 4019 = 4030
17 + 4013 = 4030
23 + 4007 = 4030
29 + 4001 = 4030
41 + 3989 = 4030
83 + 3947 = 4030
101 + 3929 = 4030

Showing the first eight; more decompositions exist.
