Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158280, here are decompositions:

11 + 158269 = 158280
19 + 158261 = 158280
37 + 158243 = 158280
47 + 158233 = 158280
53 + 158227 = 158280
71 + 158209 = 158280
79 + 158201 = 158280
137 + 158143 = 158280

Showing the first eight; more decompositions exist.
