Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154660, here are decompositions:

17 + 154643 = 154660
41 + 154619 = 154660
47 + 154613 = 154660
71 + 154589 = 154660
89 + 154571 = 154660
137 + 154523 = 154660
167 + 154493 = 154660
173 + 154487 = 154660

Showing the first eight; more decompositions exist.
