Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42080, here are decompositions:

7 + 42073 = 42080
19 + 42061 = 42080
37 + 42043 = 42080
61 + 42019 = 42080
67 + 42013 = 42080
97 + 41983 = 42080
127 + 41953 = 42080
139 + 41941 = 42080

Showing the first eight; more decompositions exist.
