Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158920, here are decompositions:

11 + 158909 = 158920
53 + 158867 = 158920
71 + 158849 = 158920
149 + 158771 = 158920
173 + 158747 = 158920
257 + 158663 = 158920
263 + 158657 = 158920
347 + 158573 = 158920

Showing the first eight; more decompositions exist.
