Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499204, here are decompositions:

43 + 31499161 = 31499204
67 + 31499137 = 31499204
97 + 31499107 = 31499204
127 + 31499077 = 31499204
181 + 31499023 = 31499204
211 + 31498993 = 31499204
241 + 31498963 = 31499204
307 + 31498897 = 31499204

Showing the first eight; more decompositions exist.
