Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488294, here are decompositions:

23 + 31488271 = 31488294
37 + 31488257 = 31488294
67 + 31488227 = 31488294
83 + 31488211 = 31488294
157 + 31488137 = 31488294
193 + 31488101 = 31488294
223 + 31488071 = 31488294
241 + 31488053 = 31488294

Showing the first eight; more decompositions exist.
