Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502336, here are decompositions:

3 + 31502333 = 31502336
7 + 31502329 = 31502336
67 + 31502269 = 31502336
223 + 31502113 = 31502336
379 + 31501957 = 31502336
457 + 31501879 = 31502336
487 + 31501849 = 31502336
577 + 31501759 = 31502336

Showing the first eight; more decompositions exist.
