Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158140, here are decompositions:

11 + 158129 = 158140
131 + 158009 = 158140
137 + 158003 = 158140
149 + 157991 = 158140
233 + 157907 = 158140
239 + 157901 = 158140
251 + 157889 = 158140
263 + 157877 = 158140

Showing the first eight; more decompositions exist.
