Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174490, here are decompositions:

3 + 174487 = 174490
23 + 174467 = 174490
47 + 174443 = 174490
59 + 174431 = 174490
83 + 174407 = 174490
101 + 174389 = 174490
179 + 174311 = 174490
191 + 174299 = 174490

Showing the first eight; more decompositions exist.
