Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172844, here are decompositions:

37 + 172807 = 172844
43 + 172801 = 172844
103 + 172741 = 172844
127 + 172717 = 172844
157 + 172687 = 172844
163 + 172681 = 172844
181 + 172663 = 172844
211 + 172633 = 172844

Showing the first eight; more decompositions exist.
