Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462230, here are decompositions:

13 + 31462217 = 31462230
89 + 31462141 = 31462230
97 + 31462133 = 31462230
103 + 31462127 = 31462230
127 + 31462103 = 31462230
223 + 31462007 = 31462230
227 + 31462003 = 31462230
251 + 31461979 = 31462230

Showing the first eight; more decompositions exist.
