Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172894, here are decompositions:

11 + 172883 = 172894
17 + 172877 = 172894
23 + 172871 = 172894
41 + 172853 = 172894
107 + 172787 = 172894
173 + 172721 = 172894
251 + 172643 = 172894
311 + 172583 = 172894

Showing the first eight; more decompositions exist.
