Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172974, here are decompositions:

5 + 172969 = 172974
41 + 172933 = 172974
97 + 172877 = 172974
103 + 172871 = 172974
107 + 172867 = 172974
167 + 172807 = 172974
173 + 172801 = 172974
223 + 172751 = 172974

Showing the first eight; more decompositions exist.
