Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169040, here are decompositions:

31 + 169009 = 169040
37 + 169003 = 169040
97 + 168943 = 169040
103 + 168937 = 169040
127 + 168913 = 169040
139 + 168901 = 169040
271 + 168769 = 169040
367 + 168673 = 169040

Showing the first eight; more decompositions exist.
