Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172392, here are decompositions:

19 + 172373 = 172392
41 + 172351 = 172392
61 + 172331 = 172392
71 + 172321 = 172392
79 + 172313 = 172392
109 + 172283 = 172392
113 + 172279 = 172392
149 + 172243 = 172392

Showing the first eight; more decompositions exist.
