Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172436, here are decompositions:

3 + 172433 = 172436
13 + 172423 = 172436
37 + 172399 = 172436
79 + 172357 = 172436
139 + 172297 = 172436
157 + 172279 = 172436
193 + 172243 = 172436
223 + 172213 = 172436

Showing the first eight; more decompositions exist.
