Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4240, here are decompositions:

11 + 4229 = 4240
23 + 4217 = 4240
29 + 4211 = 4240
83 + 4157 = 4240
101 + 4139 = 4240
107 + 4133 = 4240
113 + 4127 = 4240
149 + 4091 = 4240

Showing the first eight; more decompositions exist.
