Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158742, here are decompositions:

11 + 158731 = 158742
43 + 158699 = 158742
79 + 158663 = 158742
109 + 158633 = 158742
131 + 158611 = 158742
151 + 158591 = 158742
179 + 158563 = 158742
191 + 158551 = 158742

Showing the first eight; more decompositions exist.
