Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75982, here are decompositions:

3 + 75979 = 75982
41 + 75941 = 75982
113 + 75869 = 75982
149 + 75833 = 75982
239 + 75743 = 75982
251 + 75731 = 75982
293 + 75689 = 75982
353 + 75629 = 75982

Showing the first eight; more decompositions exist.
