Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153540, here are decompositions:

7 + 153533 = 153540
11 + 153529 = 153540
17 + 153523 = 153540
19 + 153521 = 153540
29 + 153511 = 153540
31 + 153509 = 153540
41 + 153499 = 153540
53 + 153487 = 153540

Showing the first eight; more decompositions exist.
