Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604008, here are decompositions:

17 + 31603991 = 31604008
89 + 31603919 = 31604008
131 + 31603877 = 31604008
179 + 31603829 = 31604008
251 + 31603757 = 31604008
257 + 31603751 = 31604008
269 + 31603739 = 31604008
431 + 31603577 = 31604008

Showing the first eight; more decompositions exist.
