Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10428, here are decompositions:

29 + 10399 = 10428
37 + 10391 = 10428
59 + 10369 = 10428
71 + 10357 = 10428
97 + 10331 = 10428
107 + 10321 = 10428
127 + 10301 = 10428
139 + 10289 = 10428

Showing the first eight; more decompositions exist.
