Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143658, here are decompositions:

5 + 143653 = 143658
7 + 143651 = 143658
29 + 143629 = 143658
41 + 143617 = 143658
89 + 143569 = 143658
107 + 143551 = 143658
131 + 143527 = 143658
139 + 143519 = 143658

Showing the first eight; more decompositions exist.
