Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13242, here are decompositions:

13 + 13229 = 13242
23 + 13219 = 13242
59 + 13183 = 13242
71 + 13171 = 13242
79 + 13163 = 13242
83 + 13159 = 13242
139 + 13103 = 13242
149 + 13093 = 13242

Showing the first eight; more decompositions exist.
