Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5242, here are decompositions:

5 + 5237 = 5242
11 + 5231 = 5242
53 + 5189 = 5242
71 + 5171 = 5242
89 + 5153 = 5242
191 + 5051 = 5242
233 + 5009 = 5242
239 + 5003 = 5242

Showing the first eight; more decompositions exist.
