Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172874, here are decompositions:

3 + 172871 = 172874
7 + 172867 = 172874
67 + 172807 = 172874
73 + 172801 = 172874
157 + 172717 = 172874
193 + 172681 = 172874
211 + 172663 = 172874
241 + 172633 = 172874

Showing the first eight; more decompositions exist.
