Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173828, here are decompositions:

157 + 173671 = 173828
181 + 173647 = 173828
199 + 173629 = 173828
211 + 173617 = 173828
229 + 173599 = 173828
331 + 173497 = 173828
337 + 173491 = 173828
397 + 173431 = 173828

Showing the first eight; more decompositions exist.
