Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604082, here are decompositions:

31 + 31604051 = 31604082
149 + 31603933 = 31604082
151 + 31603931 = 31604082
163 + 31603919 = 31604082
193 + 31603889 = 31604082
239 + 31603843 = 31604082
281 + 31603801 = 31604082
331 + 31603751 = 31604082

Showing the first eight; more decompositions exist.
