Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168424, here are decompositions:

71 + 168353 = 168424
101 + 168323 = 168424
131 + 168293 = 168424
197 + 168227 = 168424
227 + 168197 = 168424
281 + 168143 = 168424
353 + 168071 = 168424
401 + 168023 = 168424

Showing the first eight; more decompositions exist.
