Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75278, here are decompositions:

61 + 75217 = 75278
67 + 75211 = 75278
97 + 75181 = 75278
109 + 75169 = 75278
199 + 75079 = 75278
241 + 75037 = 75278
337 + 74941 = 75278
349 + 74929 = 75278

Showing the first eight; more decompositions exist.
