Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173378, here are decompositions:

19 + 173359 = 173378
31 + 173347 = 173378
229 + 173149 = 173378
241 + 173137 = 173378
379 + 172999 = 173378
397 + 172981 = 173378
409 + 172969 = 173378
571 + 172807 = 173378

Showing the first eight; more decompositions exist.
