Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502322, here are decompositions:

11 + 31502311 = 31502322
43 + 31502279 = 31502322
53 + 31502269 = 31502322
79 + 31502243 = 31502322
109 + 31502213 = 31502322
139 + 31502183 = 31502322
191 + 31502131 = 31502322
193 + 31502129 = 31502322

Showing the first eight; more decompositions exist.
