Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153640, here are decompositions:

17 + 153623 = 153640
29 + 153611 = 153640
83 + 153557 = 153640
107 + 153533 = 153640
131 + 153509 = 153640
191 + 153449 = 153640
197 + 153443 = 153640
233 + 153407 = 153640

Showing the first eight; more decompositions exist.
