Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605016, here are decompositions:

29 + 31604987 = 31605016
83 + 31604933 = 31605016
167 + 31604849 = 31605016
227 + 31604789 = 31605016
257 + 31604759 = 31605016
269 + 31604747 = 31605016
293 + 31604723 = 31605016
389 + 31604627 = 31605016

Showing the first eight; more decompositions exist.
