Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76428, here are decompositions:

5 + 76423 = 76428
7 + 76421 = 76428
41 + 76387 = 76428
59 + 76369 = 76428
61 + 76367 = 76428
139 + 76289 = 76428
167 + 76261 = 76428
179 + 76249 = 76428

Showing the first eight; more decompositions exist.
