Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175730, here are decompositions:

3 + 175727 = 175730
7 + 175723 = 175730
31 + 175699 = 175730
43 + 175687 = 175730
67 + 175663 = 175730
97 + 175633 = 175730
109 + 175621 = 175730
157 + 175573 = 175730

Showing the first eight; more decompositions exist.
