Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172854, here are decompositions:

5 + 172849 = 172854
47 + 172807 = 172854
53 + 172801 = 172854
67 + 172787 = 172854
103 + 172751 = 172854
113 + 172741 = 172854
137 + 172717 = 172854
167 + 172687 = 172854

Showing the first eight; more decompositions exist.
