Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8242, here are decompositions:

5 + 8237 = 8242
11 + 8231 = 8242
23 + 8219 = 8242
71 + 8171 = 8242
131 + 8111 = 8242
149 + 8093 = 8242
173 + 8069 = 8242
233 + 8009 = 8242

Showing the first eight; more decompositions exist.
