Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30426, here are decompositions:

23 + 30403 = 30426
37 + 30389 = 30426
59 + 30367 = 30426
79 + 30347 = 30426
103 + 30323 = 30426
107 + 30319 = 30426
113 + 30313 = 30426
157 + 30269 = 30426

Showing the first eight; more decompositions exist.
