Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604010, here are decompositions:

19 + 31603991 = 31604010
23 + 31603987 = 31604010
79 + 31603931 = 31604010
131 + 31603879 = 31604010
167 + 31603843 = 31604010
181 + 31603829 = 31604010
271 + 31603739 = 31604010
293 + 31603717 = 31604010

Showing the first eight; more decompositions exist.
