Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158012, here are decompositions:

3 + 158009 = 158012
13 + 157999 = 158012
61 + 157951 = 158012
79 + 157933 = 158012
181 + 157831 = 158012
199 + 157813 = 158012
241 + 157771 = 158012
373 + 157639 = 158012

Showing the first eight; more decompositions exist.
