Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4238, here are decompositions:

7 + 4231 = 4238
19 + 4219 = 4238
37 + 4201 = 4238
61 + 4177 = 4238
79 + 4159 = 4238
109 + 4129 = 4238
127 + 4111 = 4238
139 + 4099 = 4238

Showing the first eight; more decompositions exist.
