Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938242, here are decompositions:

23 + 938219 = 938242
59 + 938183 = 938242
113 + 938129 = 938242
191 + 938051 = 938242
251 + 937991 = 938242
293 + 937949 = 938242
359 + 937883 = 938242
401 + 937841 = 938242

Showing the first eight; more decompositions exist.
