Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158040, here are decompositions:

11 + 158029 = 158040
23 + 158017 = 158040
31 + 158009 = 158040
37 + 158003 = 158040
41 + 157999 = 158040
89 + 157951 = 158040
107 + 157933 = 158040
109 + 157931 = 158040

Showing the first eight; more decompositions exist.
