Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173542, here are decompositions:

3 + 173539 = 173542
11 + 173531 = 173542
41 + 173501 = 173542
59 + 173483 = 173542
113 + 173429 = 173542
233 + 173309 = 173542
251 + 173291 = 173542
269 + 173273 = 173542

Showing the first eight; more decompositions exist.
