Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173538, here are decompositions:

7 + 173531 = 173538
37 + 173501 = 173538
41 + 173497 = 173538
47 + 173491 = 173538
107 + 173431 = 173538
109 + 173429 = 173538
179 + 173359 = 173538
181 + 173357 = 173538

Showing the first eight; more decompositions exist.
