Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175390, here are decompositions:

29 + 175361 = 175390
41 + 175349 = 175390
113 + 175277 = 175390
179 + 175211 = 175390
311 + 175079 = 175390
401 + 174989 = 175390
431 + 174959 = 175390
461 + 174929 = 175390

Showing the first eight; more decompositions exist.
