Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172274, here are decompositions:

31 + 172243 = 172274
61 + 172213 = 172274
103 + 172171 = 172274
127 + 172147 = 172274
181 + 172093 = 172274
337 + 171937 = 172274
397 + 171877 = 172274
463 + 171811 = 172274

Showing the first eight; more decompositions exist.
