Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4050, here are decompositions:

23 + 4027 = 4050
29 + 4021 = 4050
31 + 4019 = 4050
37 + 4013 = 4050
43 + 4007 = 4050
47 + 4003 = 4050
61 + 3989 = 4050
83 + 3967 = 4050

Showing the first eight; more decompositions exist.
