Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91428, here are decompositions:

5 + 91423 = 91428
17 + 91411 = 91428
31 + 91397 = 91428
41 + 91387 = 91428
47 + 91381 = 91428
59 + 91369 = 91428
61 + 91367 = 91428
97 + 91331 = 91428

Showing the first eight; more decompositions exist.
