Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75782, here are decompositions:

61 + 75721 = 75782
73 + 75709 = 75782
79 + 75703 = 75782
103 + 75679 = 75782
163 + 75619 = 75782
199 + 75583 = 75782
211 + 75571 = 75782
229 + 75553 = 75782

Showing the first eight; more decompositions exist.
