Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158706, here are decompositions:

7 + 158699 = 158706
43 + 158663 = 158706
59 + 158647 = 158706
73 + 158633 = 158706
89 + 158617 = 158706
109 + 158597 = 158706
139 + 158567 = 158706
179 + 158527 = 158706

Showing the first eight; more decompositions exist.
