Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172074, here are decompositions:

5 + 172069 = 172074
43 + 172031 = 172074
47 + 172027 = 172074
53 + 172021 = 172074
73 + 172001 = 172074
127 + 171947 = 172074
137 + 171937 = 172074
151 + 171923 = 172074

Showing the first eight; more decompositions exist.
