Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75820, here are decompositions:

23 + 75797 = 75820
47 + 75773 = 75820
53 + 75767 = 75820
89 + 75731 = 75820
113 + 75707 = 75820
131 + 75689 = 75820
137 + 75683 = 75820
167 + 75653 = 75820

Showing the first eight; more decompositions exist.
