Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534230, here are decompositions:

31 + 31534199 = 31534230
43 + 31534187 = 31534230
47 + 31534183 = 31534230
61 + 31534169 = 31534230
89 + 31534141 = 31534230
109 + 31534121 = 31534230
113 + 31534117 = 31534230
127 + 31534103 = 31534230

Showing the first eight; more decompositions exist.
