Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604416, here are decompositions:

29 + 31604387 = 31604416
59 + 31604357 = 31604416
113 + 31604303 = 31604416
197 + 31604219 = 31604416
227 + 31604189 = 31604416
317 + 31604099 = 31604416
359 + 31604057 = 31604416
383 + 31604033 = 31604416

Showing the first eight; more decompositions exist.
