Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173490, here are decompositions:

7 + 173483 = 173490
17 + 173473 = 173490
59 + 173431 = 173490
61 + 173429 = 173490
131 + 173359 = 173490
181 + 173309 = 173490
193 + 173297 = 173490
197 + 173293 = 173490

Showing the first eight; more decompositions exist.
