Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158090, here are decompositions:

13 + 158077 = 158090
19 + 158071 = 158090
43 + 158047 = 158090
61 + 158029 = 158090
73 + 158017 = 158090
139 + 157951 = 158090
157 + 157933 = 158090
193 + 157897 = 158090

Showing the first eight; more decompositions exist.
