Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31430, here are decompositions:

37 + 31393 = 31430
43 + 31387 = 31430
73 + 31357 = 31430
97 + 31333 = 31430
103 + 31327 = 31430
109 + 31321 = 31430
163 + 31267 = 31430
181 + 31249 = 31430

Showing the first eight; more decompositions exist.
