Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4048, here are decompositions:

29 + 4019 = 4048
41 + 4007 = 4048
47 + 4001 = 4048
59 + 3989 = 4048
101 + 3947 = 4048
131 + 3917 = 4048
137 + 3911 = 4048
167 + 3881 = 4048

Showing the first eight; more decompositions exist.
