Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143538, here are decompositions:

11 + 143527 = 143538
19 + 143519 = 143538
29 + 143509 = 143538
37 + 143501 = 143538
61 + 143477 = 143538
71 + 143467 = 143538
137 + 143401 = 143538
151 + 143387 = 143538

Showing the first eight; more decompositions exist.
