Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172552, here are decompositions:

11 + 172541 = 172552
113 + 172439 = 172552
131 + 172421 = 172552
179 + 172373 = 172552
239 + 172313 = 172552
269 + 172283 = 172552
293 + 172259 = 172552
353 + 172199 = 172552

Showing the first eight; more decompositions exist.
