Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604068, here are decompositions:

11 + 31604057 = 31604068
17 + 31604051 = 31604068
137 + 31603931 = 31604068
149 + 31603919 = 31604068
179 + 31603889 = 31604068
191 + 31603877 = 31604068
239 + 31603829 = 31604068
311 + 31603757 = 31604068

Showing the first eight; more decompositions exist.
