Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604892, here are decompositions:

29 + 31604863 = 31604892
43 + 31604849 = 31604892
89 + 31604803 = 31604892
103 + 31604789 = 31604892
149 + 31604743 = 31604892
173 + 31604719 = 31604892
211 + 31604681 = 31604892
251 + 31604641 = 31604892

Showing the first eight; more decompositions exist.
