Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31230, here are decompositions:

7 + 31223 = 31230
11 + 31219 = 31230
37 + 31193 = 31230
41 + 31189 = 31230
47 + 31183 = 31230
53 + 31177 = 31230
71 + 31159 = 31230
79 + 31151 = 31230

Showing the first eight; more decompositions exist.
