Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499234, here are decompositions:

3 + 31499231 = 31499234
7 + 31499227 = 31499234
73 + 31499161 = 31499234
97 + 31499137 = 31499234
127 + 31499107 = 31499234
157 + 31499077 = 31499234
211 + 31499023 = 31499234
241 + 31498993 = 31499234

Showing the first eight; more decompositions exist.
