Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158790, here are decompositions:

13 + 158777 = 158790
19 + 158771 = 158790
29 + 158761 = 158790
31 + 158759 = 158790
41 + 158749 = 158790
43 + 158747 = 158790
59 + 158731 = 158790
127 + 158663 = 158790

Showing the first eight; more decompositions exist.
