Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179090, here are decompositions:

7 + 179083 = 179090
61 + 179029 = 179090
103 + 178987 = 179090
139 + 178951 = 179090
151 + 178939 = 179090
157 + 178933 = 179090
181 + 178909 = 179090
193 + 178897 = 179090

Showing the first eight; more decompositions exist.
