Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15230, here are decompositions:

3 + 15227 = 15230
13 + 15217 = 15230
31 + 15199 = 15230
37 + 15193 = 15230
43 + 15187 = 15230
109 + 15121 = 15230
139 + 15091 = 15230
157 + 15073 = 15230

Showing the first eight; more decompositions exist.
