Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499270, here are decompositions:

3 + 31499267 = 31499270
31 + 31499239 = 31499270
43 + 31499227 = 31499270
109 + 31499161 = 31499270
163 + 31499107 = 31499270
193 + 31499077 = 31499270
277 + 31498993 = 31499270
307 + 31498963 = 31499270

Showing the first eight; more decompositions exist.
