Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75180, here are decompositions:

11 + 75169 = 75180
13 + 75167 = 75180
19 + 75161 = 75180
31 + 75149 = 75180
47 + 75133 = 75180
71 + 75109 = 75180
97 + 75083 = 75180
101 + 75079 = 75180

Showing the first eight; more decompositions exist.
