Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499308, here are decompositions:

11 + 31499297 = 31499308
17 + 31499291 = 31499308
41 + 31499267 = 31499308
149 + 31499159 = 31499308
251 + 31499057 = 31499308
317 + 31498991 = 31499308
359 + 31498949 = 31499308
461 + 31498847 = 31499308

Showing the first eight; more decompositions exist.
