Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4072, here are decompositions:

23 + 4049 = 4072
53 + 4019 = 4072
59 + 4013 = 4072
71 + 4001 = 4072
83 + 3989 = 4072
149 + 3923 = 4072
191 + 3881 = 4072
239 + 3833 = 4072

Showing the first eight; more decompositions exist.
