Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75980, here are decompositions:

13 + 75967 = 75980
43 + 75937 = 75980
67 + 75913 = 75980
97 + 75883 = 75980
127 + 75853 = 75980
193 + 75787 = 75980
199 + 75781 = 75980
271 + 75709 = 75980

Showing the first eight; more decompositions exist.
