Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143676, here are decompositions:

7 + 143669 = 143676
23 + 143653 = 143676
47 + 143629 = 143676
59 + 143617 = 143676
67 + 143609 = 143676
83 + 143593 = 143676
103 + 143573 = 143676
107 + 143569 = 143676

Showing the first eight; more decompositions exist.
