Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604106, here are decompositions:

7 + 31604099 = 31604106
73 + 31604033 = 31604106
173 + 31603933 = 31604106
227 + 31603879 = 31604106
229 + 31603877 = 31604106
263 + 31603843 = 31604106
277 + 31603829 = 31604106
349 + 31603757 = 31604106

Showing the first eight; more decompositions exist.
