Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604166, here are decompositions:

29 + 31604137 = 31604166
37 + 31604129 = 31604166
67 + 31604099 = 31604166
109 + 31604057 = 31604166
179 + 31603987 = 31604166
233 + 31603933 = 31604166
277 + 31603889 = 31604166
337 + 31603829 = 31604166

Showing the first eight; more decompositions exist.
