Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502342, here are decompositions:

13 + 31502329 = 31502342
31 + 31502311 = 31502342
73 + 31502269 = 31502342
181 + 31502161 = 31502342
211 + 31502131 = 31502342
229 + 31502113 = 31502342
463 + 31501879 = 31502342
523 + 31501819 = 31502342

Showing the first eight; more decompositions exist.
