Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172050, here are decompositions:

19 + 172031 = 172050
23 + 172027 = 172050
29 + 172021 = 172050
41 + 172009 = 172050
103 + 171947 = 172050
113 + 171937 = 172050
127 + 171923 = 172050
173 + 171877 = 172050

Showing the first eight; more decompositions exist.
