Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152540, here are decompositions:

7 + 152533 = 152540
79 + 152461 = 152540
97 + 152443 = 152540
151 + 152389 = 152540
163 + 152377 = 152540
229 + 152311 = 152540
337 + 152203 = 152540
457 + 152083 = 152540

Showing the first eight; more decompositions exist.
