Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168338, here are decompositions:

7 + 168331 = 168338
61 + 168277 = 168338
127 + 168211 = 168338
211 + 168127 = 168338
229 + 168109 = 168338
271 + 168067 = 168338
367 + 167971 = 168338
421 + 167917 = 168338

Showing the first eight; more decompositions exist.
