Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499322, here are decompositions:

11 + 31499311 = 31499322
13 + 31499309 = 31499322
31 + 31499291 = 31499322
83 + 31499239 = 31499322
139 + 31499183 = 31499322
163 + 31499159 = 31499322
331 + 31498991 = 31499322
359 + 31498963 = 31499322

Showing the first eight; more decompositions exist.
