Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76828, here are decompositions:

47 + 76781 = 76828
71 + 76757 = 76828
131 + 76697 = 76828
149 + 76679 = 76828
179 + 76649 = 76828
197 + 76631 = 76828
317 + 76511 = 76828
347 + 76481 = 76828

Showing the first eight; more decompositions exist.
