Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158830, here are decompositions:

53 + 158777 = 158830
59 + 158771 = 158830
71 + 158759 = 158830
83 + 158747 = 158830
131 + 158699 = 158830
167 + 158663 = 158830
173 + 158657 = 158830
197 + 158633 = 158830

Showing the first eight; more decompositions exist.
