Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172402, here are decompositions:

3 + 172399 = 172402
29 + 172373 = 172402
59 + 172343 = 172402
71 + 172331 = 172402
89 + 172313 = 172402
179 + 172223 = 172402
233 + 172169 = 172402
353 + 172049 = 172402

Showing the first eight; more decompositions exist.
