Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30428, here are decompositions:

37 + 30391 = 30428
61 + 30367 = 30428
109 + 30319 = 30428
157 + 30271 = 30428
241 + 30187 = 30428
331 + 30097 = 30428
337 + 30091 = 30428
439 + 29989 = 30428

Showing the first eight; more decompositions exist.
