Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174520, here are decompositions:

29 + 174491 = 174520
53 + 174467 = 174520
89 + 174431 = 174520
107 + 174413 = 174520
113 + 174407 = 174520
131 + 174389 = 174520
173 + 174347 = 174520
191 + 174329 = 174520

Showing the first eight; more decompositions exist.
