Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158190, here are decompositions:

29 + 158161 = 158190
47 + 158143 = 158190
61 + 158129 = 158190
113 + 158077 = 158190
173 + 158017 = 158190
181 + 158009 = 158190
191 + 157999 = 158190
199 + 157991 = 158190

Showing the first eight; more decompositions exist.
