Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158718, here are decompositions:

19 + 158699 = 158718
61 + 158657 = 158718
71 + 158647 = 158718
97 + 158621 = 158718
101 + 158617 = 158718
107 + 158611 = 158718
127 + 158591 = 158718
137 + 158581 = 158718

Showing the first eight; more decompositions exist.
