Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163040, here are decompositions:

13 + 163027 = 163040
19 + 163021 = 163040
37 + 163003 = 163040
43 + 162997 = 163040
67 + 162973 = 163040
103 + 162937 = 163040
139 + 162901 = 163040
151 + 162889 = 163040

Showing the first eight; more decompositions exist.
