Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172204, here are decompositions:

5 + 172199 = 172204
23 + 172181 = 172204
47 + 172157 = 172204
107 + 172097 = 172204
173 + 172031 = 172204
257 + 171947 = 172204
281 + 171923 = 172204
353 + 171851 = 172204

Showing the first eight; more decompositions exist.
