Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172804, here are decompositions:

3 + 172801 = 172804
17 + 172787 = 172804
53 + 172751 = 172804
83 + 172721 = 172804
131 + 172673 = 172804
197 + 172607 = 172804
251 + 172553 = 172804
263 + 172541 = 172804

Showing the first eight; more decompositions exist.
