Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123238, here are decompositions:

29 + 123209 = 123238
47 + 123191 = 123238
179 + 123059 = 123238
281 + 122957 = 123238
317 + 122921 = 123238
347 + 122891 = 123238
389 + 122849 = 123238
419 + 122819 = 123238

Showing the first eight; more decompositions exist.
