Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173478, here are decompositions:

5 + 173473 = 173478
47 + 173431 = 173478
131 + 173347 = 173478
181 + 173297 = 173478
211 + 173267 = 173478
229 + 173249 = 173478
269 + 173209 = 173478
271 + 173207 = 173478

Showing the first eight; more decompositions exist.
