Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172254, here are decompositions:

11 + 172243 = 172254
31 + 172223 = 172254
37 + 172217 = 172254
41 + 172213 = 172254
73 + 172181 = 172254
83 + 172171 = 172254
97 + 172157 = 172254
101 + 172153 = 172254

Showing the first eight; more decompositions exist.
