Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175642, here are decompositions:

11 + 175631 = 175642
41 + 175601 = 175642
149 + 175493 = 175642
179 + 175463 = 175642
239 + 175403 = 175642
251 + 175391 = 175642
281 + 175361 = 175642
293 + 175349 = 175642

Showing the first eight; more decompositions exist.
