Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84428, here are decompositions:

7 + 84421 = 84428
37 + 84391 = 84428
79 + 84349 = 84428
109 + 84319 = 84428
181 + 84247 = 84428
199 + 84229 = 84428
229 + 84199 = 84428
307 + 84121 = 84428

Showing the first eight; more decompositions exist.
